hello Otis. The unusually thick base of the bowl might suggest this was possibly a dram or toastmasters glass - perhaps not quite fully a deception piece, but certainly the bowl has been made with less than expected capacity. The thickness of this piece might also suggest it was for tavern or pub use and, again my opinion only, but I would suggest the second half of the C19 in date - so not Georgian.
This glass would have been made in three or even four pieces, and it's not uncommon to find some roughness and less than perfect joins where these separate parts came together. The grinding/polishing of the decoration is (usually) is done at an angle of ninety degrees to the axis of the stem, so facets can get quite close to joins, but I guess there's a limit to the closeness before you end up decimating a largish collar such as yours.
Hand made glasses from this period will always show the tool marks and striations, even though the piece may not be of very high quality - I'd be worried if they weren't there.
Best of luck with your new reading book - although I don't think the volume in question will give you an id for this glass, but hopefuly with help with overall knowedge. This piece is one of those very general glasses - made in their masses - and usueful to have as an example but, as before, you're never going to find a maker, or possibly even a country of origin. It might be British, but equally might not be.
I'd like someone else to give their opinion as to whether my thoughts on a dram/toastmasters glass might be valid or not - thanks
