"Of all tyrannies, a tyranny sincerely exercised for the good of it's victim may be the most oppressive. It may be better to live under robber barons than under omnipotent moral busybodies. The robber baron's cruelty may sometimes sleep, his cupidity may at some point be satiated, but those who torment us for our own good will torment us without end for they do so with the approval of their own conscience." - C.S.

To the sellers credit, the pics do clearly show the condition of the crank

I have not quite that bad BUT 3 or 4 of the balancing holes broke through the side of the counterweight. ::) It is an earlier crank too.
