A "virgin" = original dimensions crankshaft is the hardest to find and most desirable used crankshaft. Beware of your sources as there are parts sharks selling steel parts such as rebent cranks.
"Virgin" crank would imply un-used in my books, standard dimensions would be used, but polished only - not ground to M010 or M020 due to wear. Never heard of a "rebent" crank - but knowing what I know about Continental crankshafts, if you bend and then re-bend one, it's likely to be cracked. I can't imagine any reputable shop tagging such a crankshaft.
Last time I called a barnstormer's ad regarding crankshafts for an O200, he said there aren't many out there. Whenever he lists one for sale it sells almost immediately.
PM sent Anthony... I might be able to help out.
