Possibly Bristol, 1760-70
The engraved words 'No Excise' show that it was meant for cider, a serious competitor to beer in the West Country. The Government put a tax (excise duty) on cider in 1763. The owner, or manufacturer, of this glass was obviously opposed to any such tax. Some ciders were very strong, like modern 'scrumpy'.
