I saw one that starts with P37XXX and neither proofhouse nor anywhere else do I see serials starting with P.... I have seen R and S but no P....?

The P prefix stated in 1981. The serial number you listed would have placed it being made sometime in 1982.

Proofhouse generally doesn't get much past 1979 for Colts. It's a bit frustrating. However, you can call Colt, and their Customer Service Department will provide you with the ship date over the phone.
