It's all there, the flapper is a little loose, but nothing is broken or missing that I can tell. I will assume that the servo may need rebuilding after 44+ years. $180.00 shipped to 50 States or if you can pick up I'll knock the price down.
I am also very interested in the heads, and I am local, please put me in line. Would like to know date codes if possible? I'll PM you my # for contact, thanks!
