Fingers:
That's an excellent close up where the cylinder meets the forcing cone, (the flash gap). If I ever got one of those I would hold the replica to that tolerance!
I can see the tiny fissures and metal fatigue at the end of the cylinder now THAT is some sweet history.
If ya ever sell it, be sure an tell me who ya sold it to, when he goes to work, if he has dogs, what kind of alarm he has ... you know ... the USUAL!
