The first is a forged steel 292 crank which is at least .010 under on the main and rod journals. The second is a cast 272 or 292 crank.

Old School: Charley is right, the 1st one is a forged steel truck crank, which is a desirable item for some performance situations. First thing.. if it's not pitted already, get some oil & grease on it, before it's ruined!..

The 3.10" stroke cranks are marked EBU. I have never seen an EBU crank with an oil slinger. Early EC cranks didn't have slingers either.
