I just added some info to the listing, and I'm letting you all know in case you are (or plan to be) bidding on the item (7233824227):
"NEWS FLASH! I was sure that I had replaced both missing bolts on the crankset, but I was only half correct. The crank now has all 5 of the ref:25 bolts attaching the right crank arm to the adapteur. However it is still missing the 6th ref:p75 "acorn head" bolt attaching the chainring to the adapteur (at about 7:00 in the first photo). Please bid accordingly. In the meantime I am searching for the replacement bolt, or a good substitute. If I can get one I will supply it free to the buyer, but no guarantees.
Given my error in the listing, please feel free to retract your bid without penalty if you don't want the crankset short one chainring bolt!"
I hope this news doesn't spoil anyone's day but my own. Also, just in case one of you out there happens to have the "missing bolt" floating around in your orphaned parts box, I can make you a great offer on it.
