apologies Keith - regret I don't have your knowledge of B'ham breweries

glasses made with this slight optic moulding and of a cheap quality were made very commonly - often carrying an ad. in the form of a transfer or whatever, and I suppose the proximity to Stourbridge means a variety of possibly makers. I just thought that if it had a gadget mark, you could at least tie it down to the late C19.
I've a pint tankard with wording 'Ask for Taylor Walker's Barley Mow' and 'British Made'.
I think your idea of that new home is a good suggestion.
