Will list these as a pair as their story is connected. These come from the estate is a member of our local experimental aircraft club. He had at one time a twin Apache that apparently had a prop strike on one engine. That's how we ended up with three crankshafts, and three camshafts, for the two engines.  The original cam and crank from the good engine,  the replacement cam and crank... most likely from Rick Romans... and the red tagged cam and crank from the engine with the prop strike. Still also have the red ragged crankshaft, and camshaft.  We sold the two good crankshafts, and wouldn't still have these cams, except I thought the buyer who took most of the other basically complete engines needed them, but he did not. Just found out today. One of the cranks was still in a Rick Romans shipping box, obviously fine condition, but had no inspection tag. So we think one of these camshafts was purchased at the same time.
