360 Crankshaft Part Number Question

Has anyone ordered/observed a 360 CAST crankshaft from Eagle Specialty Products?

I'd like to verify that the number on the crankshaft itself is 103603580. That's the catalog part number. When I received it, the crank itself had the number 36035806123 on it.

The 6123 last four is part of the part number for a forged crank. Eagle (through Summit) has now informed me that even the cast cranks have the 6123 last four. I'd like to verify that on a known cast crank as to my simple mind those four digits appear indicative of a forged crankshaft.

If you just need to verify whether or not it's a forged or cast.... All you need to do is to gently tap the crank (NOT ON THE JOURNALS) , if its forged, the crank would ring like a bell. Cast crank wouldn't!
