not possible to be certain I don't think. These small stars were a common form of decoration post 1850, and possibly into the C20 even - much of S. & F. glass is decorated with them, and they did import glass from the Continent. The SHEARS mark underneath the foot was very common on lesser quality drinking glasses for most of the last third of the C19, but as a feature it gives no clue as to origin.
My thoughts would be that this is a pub or tavern glass from 1870 - 90 ish.
Cylinder bowls appear to be less common than, for example the more common bucket, and if you look at Tim Mills book the impression is that cylinders seem to occur earlier in the C19, although as you say, the shears mark does provide an approximate date period. I'm sure I see far more buckets, ovoids and cups than cylinders. This might be equally from the U.K. as elsewhere.
Assume you now have Tim Mills book

But you never know - could be someone out there who might know a great deal more about this piece
