So as not to drift the thread where this came up even further… @JohnD, @Chris Longhurst these are (most of) the running Triumph slot cars I have, some a little worse for wear from age and use! I have a number of unbuilt projects hiding around the place, including a Vitesse.
All are on scratch built brass chassis, except the silver TR7 which I think is on a commercial metal chassis. Bodies as follows: TR3 - home resin casting, traded, TR4 - Airfix, Dolomite - OneThirtySecond, TR7s - modified Scalextric, 13/60 - OneThirtySecond, 1200 convertible - home resin cast, mine. The rest of the cabinet is a mix of cars belonging to me and my dad.
