How to spot a hidden handgun - guide

[Frank S]

Not throwing wet towel on anyone's project; building a revolver on that scale would involve some even bigger tooling and fixtures. And that's pattern of 1858 Remington, fired by percussion cap over loose black powder, of round ball or conical bullet in .45 caliber.
Worn out tonight, resisting urge to calculate bore diameter of the model. Certainly more than a big orange.

I was thinking A close proximity scaled off of a modern reproduction with conversion cylinder might fire the 40mm grenade
modern reproduction with conversion cylinder 45 cal.

40mm grenade 1.57" cal.

But actually it turns out to be 28mm 1.1"cal. so I was off by 12mm even Nasa was off by more than that once.
