Thanks Osakabop, for answering this difficult quest.
I know that ASAMA was named from a japanese Honshu volcano

and that this factory made guitars as well.
tom holders are from "the Pearl type" but not "Pearl made" (fast lock),

and the lugs, inspired by Yamaha definitely Asama die-casted with the carving of the double volcano on it
I have posted everything I collected about ASAMA on the french forum

some pictures of the well known "14"x8"", with the "sonor-ish" lugs; on the french forum thread you will find more models

I'm looking forward for "Peters" drums, japan; very nice kits with proprietary hardware, from the mid 60's and later.
any hints ?
have a nice week end
