I have posted before (here, I think) that whilst Bob Hall's book is the best reference book that we have for Old English paperweights, the research for it is 10 to 20 years old, and it has a number of significant errors. For example, about 20 of the paperweights in the Bacchus chapter are not Bacchus. And there is a lot of fairly wild speculation about 'early' and 'late' Bacchus, and a completely mistaken assumption that any weight with a Queen's Head cane is from the Bacchus stable. And the errors about Gillinder working at Bacchus.....
But if you were planning to sell a lot of Old English weights, perhaps you might talk up the Bacchus connections, with attributions such as 'early Bacchus', 'later Bacchus' and 'possibly unique Bacchus'......?
I agree with you about the 'Old English feel' of your weight, but that is what I first felt when I bought the footed weight below a few years back (which Bob suggested was 'later Bacchus'). Now I suspect it is Belgian.
