Topic: Port glasses date id please.

[bat20]

Hi all,these two glasses were described as vintage with gadget marks,however in the flesh I noticed they have polished pontils and I think maybe older than 1860ish.The glass is leaded and good quality with 8 slice cuts per bowl standing just under 4.5" high,they are heavy for their size and surprisingly very little wear?,making me feel they have never really been used ,although they do have black in the folds and grooves?.I'm thinking 1830ish as I've seen other flared bucket bowl small glasses described as such,but as always could be way off the mark.Any thoughts?...at all?..thanks.
