Just picked up a very nice, barely shot 16ga Elsie that dates to 1924. Trying to determine chamber size. Would it’s manufacture date preclude it from being chambered in 2.75? If I insert a fired 2.75 - crimp extended of course, and it fits, can I assume it’s safe for 2.75?? Thanks for help.

This is what I use. Or could get gunsmith to check.

Chamber lengths are clearly marked for quick and accurate measurements. Additionally, this gauge also measures choke constriction.
