I believe that "sella" is singular (for "saddle") while "selle" is plural (meaning "saddles"). I don't know if there were two different manufacturers of them or if there was one firm that used two different marks. As regards the bike, Peugeot made these "Competition" and "Super Competition" frames after the phase out of the PX-10 series in the late 70's. Some were made with 531SL and some with butted 531 full frame (3 main tubes, rear stays, forks) and some with 531 butted main tubes only). Unlike the PX10's, these had braze-on cable stays. They were all very good bikes, and any of them would be a steal for $12!

On the bike, not a PX but pretty decent, and for $10 a purchase of the decade.
