this plated mark is almost certainly Sturges, Bladdon & Middletown, who started in B'ham around 1884, and were still going apparently post WW II. Of course, this doesn't help remotely with the glass, assuming even that the two parts did start life at about the same time.
When I first saw the decoration I thought it looked Czechoslovakian, especially with the gilded background the thick looking pastel coloured enamels - and suppose that could be viable still since a lot of Continental glass was imported (see Silber & Fleming bits and pieces) during the latter part of the C19. I think the enamelled dotting is quite typical of late C19 early C20 decoration, and the whole thing looks ornate enough to be late Victorian - the extent of wear might help to suggest if quite old.
Sorry, can't help with it's use though, but suspect simply an ornate vase.
