Well at first glance it might.. but I deal US signs a lot and see many of our reproductions and fantasy pieces and it does not look anything like them.
Here is the back. It appears hand hammered/ hand made. Has real patina and somebody would have to dig very deep in old records to bring this companys name up. Is this common practice in the UK to make such fantasy signs?
If it was a US sign I would be dating it at least late 1800's to early 1900's compared to old trade signs I have seen here.
