Crankshaft Identification

[Neil Verity]

I have recently aquired 3 crankshafts as part of a package deal.  All 3 are stamped "Arma Steel".  2 have the ID number 1357899 stamped on it, which from Atlantacrankshaft.com seems to be a Buick 300 crank that has been turned down to fit a Buick block (main journals ~ 2.3 inch).  The other has an ID number 1183645.  It looks like an early original Buick/rover crank but I can not match up the ID #.  Any help verifying the Buick 300 # and of course the identity of the "unknown" crank would be appreciated.

Does it look the same as the other two? Same stroke?

Ok,

Turns out the 1357899 cranks are from a Buick 300 motor.  The other one (#1183645) is still unknown but does have a smaller throw than the Buick 300 cranks.
