Bagley David 2231-2 uranium glass powder pot

This is a frosted uranium lidded pot from Hungerford arcade, size approx. 15 x15 cm. and quite heavy. Glows beautifully under UV light. I'm now sure this is the Bagley David 2231-2 pattern but with the Empress pattern type of finial and that it's a powder pot designed to hold a large powder puff as well.
