You want a bayonet match for your musket, bring it to a show. That's your best bet. I went thru 3 or more bayonets I got from dealers online years ago to match up to my Rev War Americanized Brown Bess. Gave up, took it to a show, and third to last table at the event had a period one that fit. Traded him all the others that did not fit. I lost $ but was happy in the end.
