new here and have some questions.

I'm new here so please correct me if i'm posting this in the wrong forum but I looked and this seemed to be the most appropriate. Anway, I am a metal detectorist and come accross shotgun hulls every now and then. This one looks old and was wondering if anyone could give me an approximate age? The bottom of the brass reads
REM-UMC
No 12
NITRO CLUB
Naturally this would be curved to fit on the bottom of the brass. The on the side of the brass reads REMINGTON-UMC around the brass.
this looks like a really old hull. All of the paper/or plastic (whichever one it was) is long gone but the brass still remains in tact.
thank you for any help.

The owners combined Remington Arms Co. and the Union Metallic Cartridge Co. in 1911 as Remington Arms-Union Metallic Cartridge Co. Thus the beginning of the Rem-UMC headstamp. The company was reorganized as Remington Arms Co. Inc on May 20, 1920. But the ammuntion continued to use the Rem-UMC headstamp for many more years, even after Remington was taken over by DuPont in 1934. The Nitro-Club named shell predated the merger and was UMCs low brass smokeless powder shell. Nitro-Club remained the companies low brass smokeless powder shell through at least 1923. By 1929 the companies low brass shell was called Shur-Shot. I don't have anything between 1923 and 1929 to narrow that range. So, after 1911 and before 1929.
