[CR]RE: 4 th Bottom bracket?

Hi, all members I need a help.

I picked up an early 70's Motobecane Grand Record frame set, its B/B is not;

1) not English 1.370 X 24 TPI

2) not Italian 36 X 24 F

3) not French 35 X 1 (maybe partially?)

4) maybe SWISS(?) 35 X 1, but both gear(fixed) and adjust(left) side are right(clockwise)screw thread.

Does any one this 4 th B/B set (with spindle) or at least cups for sale , or can tell me where I can find them??

Thanks in advance!
