Found this a while back. I believe it’s British but not sure. The back to it dissolved when I recovered it. The property I found it on was owned by an Englishman in the mid to late 1700’s. Being in southeast Louisiana, it could be Spanish, French, British, etc. Any help will be much appreciated!
It's a 3 piece kind with shank. They started making them ca 1835, so best guess is a Brit volunteer for the Confederates. It's probably English militia, and definitely has that tinned iron back popular ca 1835-1870's.
