Getting ready to make a purchase

I ran across a nos TTA Crank. I was sent some picture. Can anyone verify that this is a TTA crank via pics?

It appears to have the cross-drilled rod journals the TTA crank was noted for.

It looks kinda dirty to be NOS (new old stock)?

I'm under the impression that GN and TTA crankshafts were the same dimensions otherwise.

Get P/N on the casting and then measure the journals for factory specs. Also make sure it Mags good before purchase.
