Trying to figure out what this is. It's on the lid of what is ID'ed as a late 1800's Russianicon mess kit. The mess kit is well made of copper and I have been able to confirm imperial Russian marks on identical kits which also had dates in the late 1800's. This one is not the same however and I can find no similar example of either of the marks. Wondering if it is Russian or of one of the other nearby nations of the time.
