Hi,
Apart from saying I don't for one moment believe this to be a piece of W/F, I thought I ought to mention that the decoration appears not to be engraved, but unpolished cutting.
This type of cutting is much crisper when found on a piece of Powell (W/F) and with a finer finish to the matt effect. I'd agree with John that the label has probably come off a small cheap piece in order to upgrade this and massage its potential value a seller.
Sorry, not the news you want Wes.
Cheers, Nigel
