I'll give this thread a bump, as I always presumed that there was no prototypes for many of the early 'stock' models from Revel, Atlas, Bachmann Plasticville and so on - I thought they were more of a composite or pastiche of various prototypes (or maybe even a real prototype as a base, but heavily modified for molding reasons or whatever), rather than a model of a real single prototype.
Things like the Revel passenger station was reused as the basis for their schoolhouse, and their Enginehouse was the basis for the Weekly Herald and I think the Bakery also, and Lifelike's Police Station was also the basis for their bank and firehouse - you get the idea.I'd be interested to hear otherwise, as would I also like to see a website dedicated to these once-common early building kits from the 1950s and 1960s (sort of like the Tyco website I've linked to before showcasing Tyco rolling stock and operating accessories from the 1960s/1970s)
