i am the seller. i knew very little about automotos before putting this one up, but list and non-list members alike have helped out considerably.
early 1950s automoto city bike/mixte, comes with headset, bb, and seatpost and seat bolt. i have been informed by several folks that it may in fact be a 650b set up, but can't claim that for sure. in case you are interested:
