Yoshi's son also worked for Cherubim (under his Uncle Hitoshi) but during *later years*, and the shop is still producing (Keirin frames, at least). If this frame in question was produced at one of the Cherubim shops before '76 there would be at best a 50% chance of it coming out of Yoshi's, but as to who actually built it...mystery...after '76 then undoubtedly Hitoshi's shop and one of his builders. (that's how I read it, anyway )
