the pix are better in view of the dark background - you've achieved some contrast which shows details more clearly.

My opinion is that this could have only two possible uses - either for drinking or as a stem vase, and in view of what appears to be some iron/rust staining at the bottom on the inside, then perahps the latter, although I suppose it could be used as a champers flute.
The decoration looks to be poor quality wheel engraving - and regret I can't see if there is a pontil depression or a mould finish foot, and you don't divulge (always best to comment on this point as it's an important aspect of manufacture and helps to date pieces).
As to age, can't really help, but probably not that recent in view of the wear - perhaps somewhere in the first half of the C20
Whichever, I don't think its going to fund your pension.
