your pic No. 140 is good quality, and blows up without loss of definition and shows very clear details of the stem. Going by the stem only there does seem to be an indication of genuine age, but think the answer to your question is probably that it's not viable.
Since it's not possible to know the origin of this glass, then have to remember to take into account differing styles of Continent and U.K., although there is no doubt that despite the configuration of the stem this is definitely an ale glass - funnels and trumpets with wrythen bowls of this size always seem to be.
I've just looked through Stephen Parry's 'DWARF ALE GLASSES and their Victorian Sucessors' also had look at 'English Drinking Glasses' by Ronald Gabriel - and finding wrythen, ale-shaped bowls, with stems such as this one, is difficult, so presumably unusual combination.
Ale glasses with stems similar to this one are almost always accompanied by engraved bowls showing the usual hops, ears of barley etc., not wrythen decoration.
The only example I can find is in Gabriel and even that has only the quite common partial wrythen, which stops short of the rim by some distance, and is credited with a date of c. 1820, so if pushed I'd suggest this is as good a date idea as any other guess for this glass - perhaps a little later.
Perhaps this one is Continental. Typical British wrythen ales on rudimentary stems, and dating to middle third C18 (without folded feet), are mostly good lead glass and ring well.
