Imperial No. 451 Shot Glasses.

I think these shot glasses are Imperial No. 451 similar to the ones I posted a while back and identified by TallCakes. These ones have engraved leaves and flowers. I've filled them and they only hold 1 fl.oz. U.S and are 1.75" tall so I've put them next to a wine glass for comparison. They only weigh 0.7 oz./27gm. each.
