Thanks to Eric Elman, I have scans of the 1974 catalog with P, PA, PR and PX's, and can help you figure it out. Do you have only the frame or some components as well?
First thing to check is chrome on the rear stays. If it does not have it, then it is one of the three lower ones.
The PR was 3 main tubes 531dB. You can see mine

Let me know if you have high a bandwidth connection
and I can send you the scans tonight.

> Wow!! the dumpster gods have been smiling on me this week. Went divin'
Sunday and came up with a P?-10 of some kind. The bike doesn't have the nice
Nervex I see on most PX10s. I can't find a tubing sticker but I'm pretty
sure it's not 531. It does have tubulars and Stronglight alloy crankset. The
bike is very original down to ALL the dealer installed reflectors. City of
Palo Alto License sticker from 1972. Is this some "club racer" model like a
PA-10? My sister bought a PA-10 (I think that was the model) back in '72 or
'73 and that has steel cranks. Any ideas out there?
