I think you did OK on that deal and I have a kick start Iron Horse here I’d trade any day for an early Lightwin with compression numbers like those ones!
I’m pretty sure the first year three horse motors had different seals on the shafts, or at least the prop shaft, than later motors. The impeller should be the same one as used on the 5.5, 7.5 and 6 horse motors. They are quite attractive motors when they are all cleaned up.
