Old Pewter cup 2.5” diameter JAPAN. I believe this to be a very Old cup back in the early 1950's maybe even the 40's. It does have a dent on the bottom but doesn't effect it. Great looking piece from a step back in time.  It makes me wonder if this wasn't used in the war at sometime. Drinking from a stream in the middle of no wear. Please look at all pictures for details and measurements.  Thank you for looking 😀
