The seller thought it was related to black powder but was not sure. What is it?
How big is it? Jack
Vlad, it’s a powder tin cap. I’ll check who may be the manufacturer.
Edit: Hercules Powder Co. “Black Sporting” powder (FFFg size).
Wow, really cool. I have never seen the likes… interetsed in parting with one?
Fede: Thanks for the picture of can and cap. I was hard pressed to think that any U.S. powder manufacturer post 1900 would have sold powder in cans with push-on tops. A picture is truly worth a thousand words! Jack
