Lots of those companies were just jobbers and repacked imported items in thier own blister paks. Eelco, cal custom, Segal, Rocket and others had several items that were identical but were in that companies packing. Joel Rosens stuff was the same way. The little carb gears that made a vacuum carb into a mechanical carb were sold by several places so I imagine he picked up on the idea and did the same. I've seen several different versions of the finned valve covers with different writing in the center and some of those said china or japan on them and I know those were old pieces. The coolest ones I saw were on a small block and they had embossed in the middle "pro/stock". I should have bought them.
