I believe my dad had this on his Smith Mini-Plane until he upgraded the engine... upgrade would have been in the late 70's - or maybe he just changed the prop.
All I can find is an engraving on the blade, RC. No. 1 and TC. No. 691.
Does anyone have a clue on how to interpret what this would fit?
Thanks
