The aero-modelling section is succeeded by the philately section. It is manned by Gopal Singh, whose father once occupied the same post. I am given a crash course in old coins and currency notes, and their current market value. By now, however, my eyes have been drawn to a gleaming vintage car that stands at the far end of the shop. This, I figure, is one of the 38 vintage micro-cars that Mr Kumar owns. The car in question is a 1935 Rytecraft &lsquoScootacar&rsquo, the smallest vintage car in the world, and a regular participant in the Kolkata vintage car rally. The other cars&mdashpedal-driven BMWs, Rolls, Daimlers, Vauxhalls&mdashare kept in an adjacent room amidst a veritable treasure trove of mechanical curiosities. There is a pedal aeroplane from Jaisalmer, a pram, and towering over them all, like an exhibit from a J.G. Ballard novel, the derelict remains of a Taylorcraft Auster, a two-seat WWII lightplane.
