That said, the wrapover seatstays will narrow it down for the knowledgable. This is a REALLY esoteric question, but knowing the bottom bracket threading will narrow it down even more. I know of French, British and Swiss bikes with that kind of seatstay detailing, and the threading will help. The bottom bracket cups will have something stamped into them ("35 X P1" is stamped into the Swiss thread Tange bottom bracket cups sitting on my desk right now, for instance ...) so give us that info, too.

I have to disagree with caterham; this don't look Japanese to me.

And for those of you guys who haven't picked it up from the other thread: the SN is 014511.
