From the photographs I’m afraid this will remain a mystery.
Is the safe locked shut or can the inside be photographed. If the escutcheon cover was
drawn aside the shape of the keyway might help although not very likely.
It looks to be from the late 1880’s and of resonable quality judging from the escutcheon which is of much better quality than normally seen on such safes, but then this is offset by very cheap looking hinge carriages.
Although unclear from the photograph these hinge carriages are of an unusual shape but I couldn’t identify anything anyway similar except on some early S.Withers safes. The only escutcheons of roughly similar design are to be found on some Thos.Perry safes.
