A set of these has been sitting in a local charity shop for months. I have been curious about them since i first clapped eyes on them, they have a crackle glass look to them and i have several glass silver rimed pieces dating to around 1914 with similar handles, i think these may be 40's at a guess, no wear to the bases and they look well made, i think these might be impossible to date or pin a maker on them so here goes.
There 4 1/2 inches across the rim 2 1/2 inches in height and 2 7/8th inches across the base.
