Thanks, I am strongly thinking 30's too, is quite a tricky one as I can find no other examples in the shaker collecting community. heisey glass made the only other period all glass 3 piece shaker with a strainer but it's nothing like a traditional cobbler as this is.
I think your cocktail picks are great, if I find anything out about them I'll let you know, 2 most likely sources would be Lauscha region and Czech, I see a lot of glass cocktail sticks, swizzles, muddlers and glass markers and uranium ones are quite rare and is lovely to see yours, thank you.
