Identifying a caged roller big end.

[Columbo John]

Is anyone able to tell me what the following caged roller big end would fit?

It has 1.004" dia crank pins with 2.020" dia big end roller. The big end is .752" wide and the whole assembly is 2.200" wide.

This part was supplied as part of an early B40 engine in bits but doesn't fit my 41-181 conrod as the roller dia is too big. I have sourced the correct part and the crank is now re-assembled but I have this brand new crank pin which I would like to sell if I know what it fits.

Thanks in advance, John.
