My late stock '73 Paramount P-15's rear der also statess in raised lettering reads: "Le Tour" then "Schwinn Approved GT300". And as for the question Paul asked about "alternative centerpulls I might use besides the stock Wienmans [since t]he rears are a long reach even with 27" rims", the most common way that the Campy sidepulls were mounted on the P-15s was the use of a plate or 'drop bolt' from the rear brake bridge that allowed the shorter reach Campys to be mounted (there was no issue for the front brake.) I have this on mine, and I have seen it on several others. My local Paramount guru said it was SOP when they made the swop (and that many customers wanted the Campys) but did not know if it was factory supplied or simply a commonly-available part. He said that while he was working briefly on the East coast during the same time period (early 70s) he recalls the same part or bolt being used. The one on my bike matches the chrome of the frame perfectly. Of course, I will defer to the more astute Paramount owners on the group. who should have more information on this point.
