SPECIALLOI D. Stand 357.

The Pistons, which are made by Specialloid, Ltd., at Friern Park, North Finchley, London, N. 12, are made of a special aluminium alloy and were fully described in our columns in the August issue. Their use has been found considerably to improve the running of sports cars of all types, and they are favoured by a good many racing motorists as well as members of the trade, for all well-known makes of sports cars.
