Having made a replica of this lovely pre-war tinplate item (which was on display at the recent AGM), I am about to start on the construction of a second one, hopefully avoiding the mistakes I made first time around. To this end, I've been studying photographs from many sources, and have identified a significant variation. Quite apart from the three colour choices I've found, (orange base/yellow roof, all green and all light blue), there are two different sized roofs. The one which I guess to be the earliest extends almost to the very front edge of the base, the other seems to be almost an inch shorter, and ends directly above where the driveway and the pump platform meet. There may also be some difference in the overhang at the back - some roofs finish flush with the wall, and some seem to project slightly beyond, although this may be a photographic illusion. Unfortunately, I don't have access to a genuine Dinky to check. Can anyone confirm my observations, and possibly provide measurements?
