I wonder how many swear words it took to get the cotter pins out.

1020 is a grade of chro-mo steel. It was used on low-to-middling 10-speeds back in the day. Not the quality of Columbus tubing, but well above department-store grade. I believe 1020 was used on Motobecane Mirages (and maybe Nomads?) which came in mixte frames. The original weight on a Mirage was around 27-28 lb with lots of heavy steel parts, but since you've got upgraded wheels, crankset, a single rear sprocket, single chainring, no derailleurs, I'd guess your mixte now weighs.... 24 lb (maybe 23 1/2?).
