I had a black F/ FTN, 50/1.4 made in 1972, it still had the bill of sale in the case - $460~. In '72 you could drive home a new Toyota for about $1800.

If you don't have experience working on small mechanisms, as well as the proper tools and a decent work area, send it off. Get some junk cameras like old SLRs to learn on
