I agree - looking at photos, the best we can do is float some possible ( and possibly very wrong ) ideas. I would like to see what the crank would look like after a really good clean. Best totally destroyed engine I ever saw was a Super Tigre 60 control line speed engine which had a shaft run after loosing its little tooth pick prop and sucked the metal mounting bracket off its fuel tank through its very large rear venturi, managed to get it past the transfer ports and then hammered it into the top of the head from the inside. About the only usable bit left was the prop nut.
