Early Waltham Pocket Watch Movement Pat. Pinion

Interesting Waltham movement, serial number is 938131 which when entered on the database yields a different result to what this is.

It is not signed Waltham anywhere, so a private label probably for the UK market. Gold balance wheel present.

The balance is broken on this and movement is very dirty, selling for parts.

Measures 42mm on the dial and 38.6mm on reverse.
