An '81 Le Tour, with sidepull calipers instead of centerpulls? Note the crankset and brake lever similarity. But I believe it should have stem shifters. Possible these were switched along with the seatpost? Who knows? Ask about the four digit date stamp in the head badge.
I think I'd want to see this bike before bidding, so is it worth a 2-3 hour road trip up to Lagrange? The seller likes that pink saddle!!!
