Would agree with Keith about dating for the handles that are top down, indicating pre 1870, but I'd suggest lots of bubbles aren't a firm enough indicator for accurate dating. The 'kick' - in the base - is, so I'm told, for strength.
If English and from the date suggested, isn't there more of a chance that this would be lead glass rather than soda? - and the ringed pontil scar suggests a Continental origin - apparently, those glass workers often used a hollow pontil rod rather than the solid rod which was more common in the U.K. - the hollow rod presumably leaving a circular shaped scar when snapped off.
Problem is that we get so hooked on assuming glass is from the U.K., that we overlook Continental origins, where features and characteristics don't always agree date wise with British.
Who described this one as Victorian - and can you refer us to aby particular books for reference purposes for similar shapes/designs etc. for c. 1790.
sorry to be picky, but there's a lot of wishful thinking when it comes to dating as we all know, and not always easy to nail something down.
