I owned a Super LeMans very similar to yours. I think it was a '77 or '78. I bought it as a parts bike for $65 and sold it for double that once I stripped off the parts. It had Campy crankset and rear derailluer. A very nice Suntour Sprint wheelset and Suntour barcons. All those parts and more came off and I rebuilt it with parts bin components. I never did ride it but remember it weighed around 29 pounds. I did like the orange paint though.
