All I know about them is they were for sale at York and beyond my price point. When I asked why the price was so high, almost double what a typical set of Weaver cars go for, he pointed out they had interiors and figures which they did. Pretty sure they were factory but have no proof they were.
Thanks, I don't think any Weaver aluminum passenger cars came from the factory with interiors and figures. Weaver was long out of the business when MTH finally installed figures in their plastic cars, and their aluminum cars never had interiors.
