From the ebay listing for this bike:
This is a Vintage Jack Taylor Tandem Frame and Fork with a few Campagnolo parts, The bottomtube is flat for structure (almost looks ovalized for lack of a better term). The serial number is 6349. Here are the measurements Front: Center to center seat tube 50.5 cm; Center to top of seat tube 54.5 cm; Center to center top tube 57.5 cm. Rear: Center to center seat tube 49 cm; Center to top of seat tube 51.5 cm; Center to center (top tube) 59.5 cm. Campagnolo Nuevo Record Tandem Cranks (I am not sure if they are actually tandem cranks or just modified for use on a tandem). The cranks are Pantographed on the left side. 44 tooth front chain and rear on the non drive side. 54 for the big chainring on the drive side rear. Stronglight Tandem Headset. Nuevo Record Front and Rear Derailleur. On a scale of 1-10 I would have to rate this as a 5. The frame is structurally sound and I can not see any major rust. The frame and components need to be cleaned up. The frame does have some wear and could be repainted.
