Topic: 1850s Pressed Glass with pattern numbers

[neilh]

Along with a fellow collector I have recently noticed a number of pressed pieces which appear to date, from the styling, to the 1850s, and they are also numbered. Illustrated here are a sugar bowl numbered 265 and a tankard numbered 346. I also have a tumbler numbered 330. They are clearly by the same glass works. The quality of the glass and the weight suggest high end pressed glass, and I suspect they were made in the Midlands by a factory that numbered their entire tableware range.

Who could it be?

Has anyone seen any other pieces numbered in this way from the same era?
