I agree with Tubs. $400 is too much for a basket case. If the important bits are in good condition then I would pay a little more for it. Lots of Ruddertwins at Constantine with price tags from $75-200. I paid $200 for a running Ruddertwin at Suter’s meet last month.
That motor looks suspiciously familiar, and that shop floor as well….lol
