hello. Presumably your torch is producing ultra violet light, so can't imagine this isn't uranium glass.
Would be useful to see a picture of the underside of the foot, and some idea of extent of wear might help to assess age. Providing details of the height is also a usual fact which might assist.
I believe these 'pushed-in/dimpled/dented' sides were a decorative feature used during the 1920 to late 1930's period, which might tie in with your bubbled glass - assuming of course yours is period, and not repro.
I'd imagine finding a maker is probably a non-starter, but we have some clever folk here, so fingers crossed.
