Hello folder riders, this is my first post in this sub-forum! I've just (sort of) joined your ranks after finding a Moulton Mk. III on craigslist that needs a bit of work.

Among other minor problems, the seat post is not original (looks like it came from a exercise bike,) and probably slightly oversized. A previous owner addressed this by inserting it only to the bottom of the slot in the seat tube, but fortunately did not deform the tube significantly. The entire post is less than 8" long

Because the opening is a bit stretched out, I can't accurately measure it with my calipers, but I think it should be about 27mm. Can someone confirm what size post this bike will take? I believe the bike is a Raleigh-made version from 1968 or 69.

** edit: after digging around for Moulton history, I realize that this one can be no earlier than 1970...



The offending post (and offensive saddle,) when I spoke to the owner on the phone, he suggested the bike may be a Schwinn because of the saddle...
