Forged or Cast??

It's been a while since i've looked at a spare crank in my barn. And i've actually forgotten whether its forged or cast. I cant recall the casting date that was on the block either. How do you determin cast or forged?

bump! nobody knows how to tell the diff?

the cast is going to have a thin parting line down the center wereas the forged unit has a wide parting line
the cast also has sharper more squared off corners while the forged is nice and rounded

cool thanks.
