I am excited to discover the trek I purchased for parts isn't a mid end 510/520 model. After taking it a part I noticed it has Campagnolo drop outs! It has great finish work between the stays and the dropouts. Let me know your thoughts.

I can Not find a serial number but under the bb shell it says F4. seatpost size is 27.0 and the approx. wheel base on this 24 inch frame is 41 inches. My gut says its an old 730 but that was built before my time selling trek in the 80s

Please advise... Thanks
