fair price for a used crankshaft

[James Harwood <james.harwood@sbcglobal.net>]

Hi Listers,
I have been offered a replacement 5 main crankshaft
for my 1974 MGB by a friend. The crank is in good
condition, has been ground down .020 and .010, and has
been balanced.
My friend just wants a fair price for it, but neither
of us have any idea what that price would be.

Any suggestions would be very much appreciated.
