Large copper driving band identification request



please help to identify this copper driving band. Because of its size it was most likely fitted to a shell of at least 21cm or 24cm caliber. In my opinion it looks rather American than German, what do you guys think?
Unfortunately I could not find anything in my archive …

Thanks very much for any help!


This one looks typical British and is likely form a 15 inch navy shell.



I only see the word “Image”, but not the image itself !?
