Hello Roy........ Assuming for a moment that this is British, then it's fairly safe to say that this would have been made prior to c. 1860 - based on the method of handle attachment - it has the squiggly finial at the lower end.
Would Pamela care to comment if Continental handles follow the same two forms of attachment as the British pieces, and would they also have had a similar date line for the change from one style to the other?
My reason for commenting really was to say that there is a sugar bowl showing in Raymond Notley's 'Popular Glass of the 19th and 20th Centuries' (page 9) which although not the same design pattern of massive pillars, does have identical scalloped/petaled feet - and although Notley's is unmarked, he attributes his to being English and gives a date of 1845. Your idea of date is therefore, possibly, not far out.
Both Slack and Lattimore also show single examples of sugars with similar feet, which they attribute to Ed. Moore.
Equally, Pamela could be correct with the suggestion of Continental.
