You are correct, Gregory Kluck...... the Minicraft Rolls-Royce was previously a Hubley promo, both in plastic. I have an original Hubley promo and many Minicraft kits, but I think the above topic is talking about metal scale model cars, so not the plastic ones. I believe the tooling has passed from Minicraft to China, but I may be wrong, and it is possible that Minicraft still own the tools. The company does still exist in Rockford, Illinois, USA.
Don't know if this helps you at all, Greg Hasselbach..... just thought I would add what I know. Although I would be interested in old Hubley models, they would have to be Rolls-Royce..... sorry.
