15/16 breech plug needed

[wesred101]

searching for a tc 11/16-20 flint breech plug can’t find one any where next option is a 11/16/20 oil drain plug and rounding the tang out to fit it and drilling the barrel for the touch hole liner would love not to have to go that route… this barrel I have is definitely a interesting one.. tc 45 caliber low 4 digit 2131 with a star on the bottom of the barrel was told this came out of the custom shop in the 70s

I cut it off and made it 5/8-18”. I found the search to be hopeless after a few months. It’s a flint lock barrel now.

There's a member here who machines those breech plugs and offers them in the classifieds. A search there should turn them up.
