Nice to see some good original, old percussion cap tins. Thank you for posting them. The 'UMC' is early to late 1900s. I used to use this brand when I would shoot some. The lower is a Japanned English tin and dates to the mid 1800s, as this is often the type that Colt used in some cased revolver set ups. Nice to see one in really good condition. They often are heavily flaked and scratched.
