Got this rather attractive little amber divided dish a few days ago, but haven't been able to come up with the maker/country despite my search.
It is quite heavy - about 1/2 kg - and is 45mm deep, 145mm across. It stands on 3 small feet, all flat with significant wear. The inside has got a triangular shape... I wish I knew how to describe the piece more proficiently, but my glass vocabulary and knowledge is lacking.

Hopefully my photos will help.
Thank you for looking.
