Can somebody check a big block Chrysler crankshaft dimension for me?

This picture is my Callies 4.500" crankshaft. I am interested in comparing the 2.150" dia dimension to other's crankshafts.
It would be nice to check a factory 440 or 383 crankshaft, an Eagle, Ohio Crankshaft, etc.

I don't need an exact measurement accurate to 0.001", even within 0.010" would be useful to see if manufacturers are making this section different.

Thanks in advance,
Jim
