DH1 has been kind enough to entrust the sheet metal pieces from two seats to me to recover for his Elec-Trak tractors. One is a seat that appears to be a style that was used on other tractors such as Bolens, Ford and Wheel Horse - attached are a few pictures of the Bolens one that I recovered several months ago. The other seat is a similar two piece design but the backrest part does not move up and down.
I had a chance to start on the backrest for the second style seat today. Got the padding cut, glued on and then made a cover and glued it on.
