certainly an ale glass, and may have been cut down, but not impossible for this to have been its original height. Not sure that I understand if you're saying the rim is cut similar to non-British examples, then bevelled, or just bevelled. Continental glasses often have a cut and bevelled rim as opposed to the British fire polished finish. Just looked at the ten cut examples I have and the height varies from 7.25" to 7.75". I don't have sufficient Continental examples to say whether those are shorter, on the average, or not.
These slender cut thumb print ales are fairly common, and l also thought they were flower vases when I first saw one - they're even more common in their pressed form.
The lenses are refered to usually as 'punties' - which apparently comes from their similarity to the circular deperession found under the foot, where the pontil scar was removed (punty being an equivalent to the punty rod which was responsible for leaving the scar).
The lenses are circular usually, although occasionally oval, and rarely you'll find a previous owner's name up near the rim, scratched on with diamond point.
The lenses seem to vary a lot, and there might be as few as three bands, or as many as six, but they always appear neat and well done, unlike the pressed examples which as you'd imagine are rather blotchy.
Date wise, these slender sorts with fairly bright glass date from the earlier part of the last quarter of the C19, probably, but I have to be honest and say that my ideas for this come from the pressed examples, which can be found in catalogues from the pressed glass factories - Sowerby for example.
As a form of decoration on pub/tavern glasses, these cut lenses seem to have been common throughout most of the Victorian period, but as far as I'm aware not earlier than that ....... other than perhaps some slightly similar 'hollows'. I have other similar cut thumb print ales - shorter and darker in colour - plus some rummers which I am inclined to think date more to the early to mid Victorian period, rather than the later period of these tall examples. Dating some of these pub/tavern ale glasses is not easy - some might show scars, others have ground pontils and yet others again have that 'swirl' finish under the foot (more an indication of c. 1900, I think.)
But fairly safe to say examples like yours are around the 1870 - 1880 period - but certainly not Georgian.
Good to collect, smallish footprint, not too expensive, and as Peter would say, 'you can use them'. sorry this is long winded
