So based on feedback and additional research here's where I'm at: Model P13 and the serial number indicates March 1973 205th frame built. Wheels and pedals wrong. 20" (50.8 cm) frame. I'll totally disassemble this bike and clean but prefer to avoid paint touch-ups. I may re-decal the "Schwinn Paramount" down tube decals though. I see prices all over the place and realize size, color, correctness factors into value. I'm just trying to decide if its worth buying the correct wheelset and pedals so any idea of what this may be worth correct would be much appreciated. Thanks, Shawn
