The 12/50 and 12/60 models remain unaltered for 1933, the chief features of the car being the push rod o.h.v. engine, with 3-bearing crankshaft and aluminium alloy pistons, coil ignition, single plate clutch, four speed gear box, right-hand change, open propellor shaft, and semielliptic springs front and rear. The tank capacity is 10 gallons, wheelbase 9ft. 4ins. and track 4ft. 2ins. The 12/60 sports model differs from the 12/50 in having a higher compression ratio, two carburettors, close ratio gear box and special rear springs. An entirely new model, the ” Firefly ” has been introduced, the principal features of which are as follows : 11.9 h.p. 4 cylinder engine, 1,496 c.c. 3-bearing crankshaft, connecting rods with special antifriction bearings die cast into position, aluminium alloy pistons, Duplex chain driven camshaft and auxiliary drives, lubrication by rotary geared pump, coil ignition, single plate clutch, 4 speed gear box with central change and silent third gear, tubular cordon shaft, full floating rear axle, 14in, brake drums, semielliptic springs all round, mulerslung at rear, dropped frame, 14,5 gallon rear tank, 9′ 10i” wheelbase, 4′ 6″ track. The whole car is built on the lines of the “Speed Twenty” and is very attractive in appearance. A fuller description and road test, of this interesting car will appear in a forthcoming issue of Murroa
The ” Silver Eagle” 16.95 h.p. and 19.28 h.p. models are high grade luxury cars, intended for comfort and quietness rather than speed, although their performance, in view of the weight of the bodies, is remarkable.
The ” Speed Twenty” has found to be so popular that it is being continued for 1933 absolutely unchanged, a great tribute to the forethought given to its initial design. The engine is a 6 cyl. of 2,511 c.c., with push rod operated o,h. valves, giving a very high performance to the car on the road, and a maximum speed of over 90 m.p.h. A full road test of this car appeared in our issue of June last.

No alterations are announced by Aston Martin Ltd., in their 1933 models. There are three types of the same chassis, the International 4-seater, the Le Mans 2seater, and the saloon. The specification in all cases is fundamentally the same, namely, a four cylinder engine with chain driven overhead camshaft, a Nitralloy crankshaft carried in 3 bearings, 2 S. U. carburettors, and lubrication assisted by a scavenger pump, in addition to the normal pump, which carries the oil to a tank carried between the dumb irons ; single plate dry disc clutch, 4 speed gear box, 2nd and 3rd gears being in constant mesh, open propellor shaft, bevel axle, and frame braced by six cross members.

One new model is announced by F;ttore Bugatti for 1933, the 3.3 litre, which has a single camshaft engine reminiscent of the old 3 litre car. This model is intended for fast touring work, combining flexibility with speed, and is suitable for closed coachwork. The remainder of the range consists of the 2.3, 4.9 and 5 litre cars which are already well known. A road test of the Type 55 2 seater, which appears on the stand at the Show, was published in our July issue. The racing edition of this car, the type 51, together with the racing edition of the 4.9 cars, are the machines raced officially by the firtrl this year, and also by Earl Howe.
The” Royal” chassis, more commonly known as the ” Golden Bugatti, is only made to special order, and does not therefore appear on the firm’s list. It has a 10 litre 8 cylinder engine, rated at 77.4 h.p. and is capable of 90 m.p.h. in second gear. The price is £6,500.
Prices of the other models are not yet available.

A.F.N. Ltd., London Road, Isleworth, Middlesex.
Main engine type : 4 cyl., 69 x 100 mm., 1,496 c.c., o.h.v., 11.9 h.p.
This engine can be supplied with either one or two carburettors, as in the case of the 12/45 ” Exeter ” short chassis, and the 12/50 ” Colmore ” Long chassis ; or it can be specially tuned to owners requirements as in the T.T. Replica model ; or it can be fitted with a Powerplus supercharger, as in the Nurburg model.
The Frazer Nash car is unlike any other sports car made today, in that owners’ individual requirements can be met to a degree impossible in other makes. This is largely due to the chain-drive transmission, which permits of a wide range of gear ratios without heavy expense. Incidentally, 3 speeds are normally provided on the ” Cohnore ” and “Exeter,” £20 extra being charged for 4 speeds. As stated above the engine for all models is fundamentally the same, namely a push rod operated overhead valve 4-cylinder of 1,496 c.c. capacity, and any degree of tune can be selected, from the single carburettor model, which develops 45 h.p. at 4,000 r.p.m. ; the 2 carburettor model, which develops 50 h.p. at 4,000
r.p.m. ; the normal T.T. Replica model, developing 60 h.p. at 4,000 r.p.m. ; to the supercharged Nurburg model, which develops 105 h.p. at 4,500 r.p.m.
The bodywork on all models is beautifully proportioned, and is coachbuilt in all cases. The ” Exeter” is a 2/3 seater, with a wheel base of 8′ 6k” and overall length of 12′, the Colmorc is a 3/4 seater, wheelbase 8′ 6″, and 11′ 6″ overall length, the T.T. Replica a 2 seater, wheelbase 8′ 6″ and overall length 11′ 6″, and the ” Nurburg ” a 2 seater, 8′ 61,” wheelbase and 12′ 3i” overall length.
To amplify still further the maker’s claims of meeting individual requirements, any combination of engine and body can be supplied, giving an extraordinarily wide range of models.
” Exeter ” : 2/3 seater, £399. ” Colmore ” : 3/4 seater, £499.
” T.T. Replica” : 2 seater, from £445.
” Nurburg ” : 2 seater, from £650.
Invitta Cars, The Fairmile, Cobham, Surrey.
12/45, 12/90 and 12/100 h.p. : 6 cyl., 57 x 97.9 mm., 1,497.9 c.c., 12 11.p.
14/120 h.p. : same design, but slightly larger, giving 14 11.p. engine. 41 litre : 6 cyl., 88.6 x 120 mm., 4,467 c.c., 29.12
5 litre : Special sports, details on applieltion.
Stand No. -65. Exhibits : 12/45 h.p. Chassisand Saloon ; 1 2/./0 (supercharged), Special de luxe Saloon and open 4 seater ; 12/100 h.p. (supercharged), open 4 seater and 4i litre sports chassis.
The Invicta programme for 1933 is of extraordinary interest. TO b:tgin with there is the new superchargA 12/9D model, a road test of which appears in this issue. The 12.’45 hip. car is a smooth, flexible, touring car, but the addition of the Powerplus blower in the 1290 model gives the performance a s,)arkle of ultra sporting type, without sacridcing the more gentle attributes of the car.
The 12/100 h.p. model represents automobile design in its Most modern form, and the engine is fitted with a double overhead camshaft and blower. In addition, hydraulic brakes and a Wilson pre-selective 4 speed gear box bring the car into line with the most advanced practice.
The 5 litre supercharged sports model follows similar lines, except that a 5 speed Wilson gear box will be used, giving the car a terrific maximum speed on Continental Straight “legs.” Both these cars are a direct answer to Continental competition in the expensive super sports market, and should worthily uphold British prestige.
Finally, the 4i litre sports car remains unchanged, together with the Type ” A ” luxury cars.
12/45 h.p. : 4 seater, £399; Saloon £435.
12/90 h.p. : 4 seater, £498; Saloon, £535; de luxe £575. 12/100 and 14/120 : Chassis, £645; 4 seater,

Chief alterations from the 1932 Midget, apart from the entirely new body with cut-away sides and racing rear-tank, lie in the new type cylinder head, with two new S. U. carburettors. The dynamo is driven by the vertical shaft of the camshaft drive, new small 14 mm. plugs are now used, and larger water spaces, giving
improved cooling, are provided. Also, a 4 speed gear box, with silent third, is a great improvement, and the whole car bears signs of being evolved from racing experience. The Magna is now fitted with 12in. brake drums instead of 8in. as heretofore, and other improvements consist of a modified cylinder head, and water manifold. Three types of body are listed on this chassis, a sports tourer, a sliding roof Foursome, and a new sports 2 seater similar to the new Midget, with cut-away
sides and a racing rear petrol tank.

Clement Talbot, Ltd., Barlby Road, London, W.10. ” 65 ” : 6 cyl., 61.x 95 MM., 1,666 c.c., 13.9 h.p. “75 “and” 90 ” : 6 cyl., 69.5 x 100 ram., 2,276 c.c., 17.9 h.p. “
95″ and ” 105 ” : 6 cyl., 75 x 112 ram., 2,969 c.c., 20.9 h.p.
Stand No. 55. Exhibits : ” 65 ” Saloon, “65 ” Coupe, ” 75 ” Saloon, ” 95 ” Saloon, ” 105 ” Chassis. The Talbot programme for 1933 retains its successful touring cars the ” 65 ” and the ” 75 ” with little modification, likewise the” 90″ and the” 105 “. All these
cars have six cylinder engines with push rod operated overhead valves and seven bearing crankshafts on the three larger models. A new model is the ” 95,” fitted with the 2,969 c.c. engine of the ” 105 “, but with lower compression ratio and back axle ratio and modified camshaft. A ten-foot chassis allows commodious closed coachwork to be fitted, and the resulting combination should be ideal for fast touring.
The transmission has been revolutionised by the introduction of a ” selfchanging accelerating gearbox,” which is optional at no extra charge on all models except the long “75.” Working on the Wilson epicyclic principle, it is designed and made throughout by the Talbot factory, and retains the important feature of lubrication from the engine supply, an independent pump feeding the bearings even when the car is coasting with engine stopped. The engine lubrication system is now extended to the road springs.
Last and not least, prices have been greatly reduced, making the value for money even greater than before.
” 65 ” Chassis, £295. “75 ” Chassis, £393. “90 ” Chassis, £425. ” 95 ” Chassis, £475. ” 105 ” Chassis £525. Open bodies to order.

Wolseley Motor Co., Ward End Works, Birmingham. Special : 6 cyl., 57 mm. x $3 mm., 1,271 c.c., 12 h.p. This extremely successful small car is continued for 1933 with few alterations. The six-cylinder engine employs an over
head camshaft driven by chain, two S.U. carburettors and coil ignition. Hardened cylinder liners and a new type of piston are standard for 1933. A flexible centre single plate clutch transmits the drive to a four speed and reverse gear box, thence through an open propellor shaft to a bevel driven back axle. The transmission has been strengthened throughout to deal with the extra power developed.
Semi-elliptic springs are fitted all round, with Luvax shock absorbers, and the hydraulic brakes operate on 12 inch drums. The track of the rear axle is now the same as that of the front, that is, 3ft. 9ins., allowing more room for the rear passengers or luggage without overhang.
The Hornet Special is only produced as a chassis, and will not appear on the Wolseley stand, but examples of the finished car will be exhibited by various coachbuilders.
Chassis Price, £175.
