Ralf that is a big help and helps confirm that star was mostly the maker of the badge with " world's supreme quality " written on. If that is the case, and they were the only ones who made those badges. That's at least one good slice of info that can very useful.
Ralf - you also had some badges with names that I didn't even have on my list. So far I've reached 144 different names. Thankfully I've been able to label some as Star, Hoshino, & Pearl. The real trick is figuring out when certain names switched over. Good example is U.S.Mercury. The badge you have screams Star. Where as the kit and badge I own scream Pearl. Has Pearl lugs,mounts, the works. So I wouldn't be shocked that when Star switched to Tama, that was one of the names Pearl picked up. Looks like ti happened on a few instances. Perhaps those names were being asked?
I've got some things kicking about my head. Gonna see if any of them retain water, and I'll make a post later.
