Would part numbers do it?
Pretty tough to tell, both are steel, just different manufacturing methods.
Might tell by sparks from a grinding wheel- how the carbon "feathers" and
such. the carbon grain size should differ some, might translate into a cheap
easy grinder wheel way to tell them apart.
On the unmachined surfaces, it looks a tad different- forgings are usually
Forged is so much stronger due to steel grain size and orientation. Castings
are bigger random grains, forgings are smaller, layered grain structure-
like it was "packed" into the mold, which it was. The way the carbon is
distributed is supposed to be slightly different too.
