So I also went to the Flea bay site and there is another 1968 P 13 for sale as a frame and fork. Correct decals and lugs. Easy to compare, the only braze on is for the rear derailleur. But when I look at the pics for the $1300 bike the serial number is on a bright red frame and not a maroon frame as in the pics. There is just too much wrong with this bike to even consider buying it.
I sent a querry to the seller about the matching serial number on the frame and the fork. I got the reply that in this era the serial number was only stamped on the rear dropout. So in my mind this is one to avoid!
Again JMHO, MH
