A I lampshire reader asks whether his 1929 Singer Porlock is the only one of its kind in daily use. It was bought new by his parents and has been run regularly, apart from one year’s rest, ever since, including during the war years. A Lancaster reader seeks the history of what he believes to be the sole surviving Singer Le Mans team-car, a 1934 model, AVC 484, chassis 62799, engine 59745, first registered June 1935. It is alloy-bodied, with long tail containing a 40-gallon tank, there is a tachometer but no speedometer, the back axle has splendidly noisy straight-cut gears and it is thought to have been driven at Shelsley Walsh, etc., by A. McDonald. Any clues or comments?
