Need to ID some vintage John Deere crankshafts

[Dave1953]

I have some Deere cranks from the 1970's, 1980's that were at a former JD dealer that they had for resale. This dealer went belly up about 10 years ago. The only way I know how to ID them is by their casting numbers. Does anyone know of a source of casting numbers where I might find out what machine these fit? Thanks in advance.

I might be interested in a JD 950 crank if you get them ID’d. 3 cylinder Yanmar 3T90J. The 950 connecting rods have a zillion different casting numbers. I assume each lot was a different number. When I was looking for a rod I never found 2 used rods with the same number.
