does anyone know if old c itoh (bridgestone before it was bridgestone) frames used something other than english threaded bottom brackets? I sold one on ebay, assuming it was english and having never checked for sure, and now the buyer is telling me standard english cups are too small. Anyone have one of these frames?
It seems weird a japanese company would have used anything other than english threading, but what do i know..

My late '70s Itoh has standard english bb threading.
It has an english thread bb lockring on the rear hub too...
