Oddly this is stated to be 1891 (presumably from the lock serial numbers) but has 2 plaques celebrating awards from 40 years before... and the escutcheon says Bolton but they didn’t move there until 1928
the factory could have refurbed a new escutcheon on an old safe, but it makes you wonder about the 2 plaques.
