Anyone know headstamps?

[Older The Better]

I’ve been cataloging finds and I was looking to narrow down the age of this .410 shell, being Winchester i didn’t think it’d be this difficult. I can’t find hardly anything on a shell marked with .410 -12 mm The best I can find is a site where the pics are gone but a poster says 1916-1930 something. Cartridge corner doesn’t have one with the 12mm that I could see… maybe someone here has already found out about this stamp and can help me out… if I had to guess with no made in USA 1916-1926.

While you are waiting for a member(s) to pipe in = I searched Google and found and interesting article - Pre-Historic .410s - The .44 Shot Cartridges. Doesn't answer your question but is interesting.

I gleamed this off another site.

that was the only thing I found too. I just didn’t like that the pics were gone. Because sometimes there’s variations but they seemed knowledgeable enough and that was what I was basing my guess on.
