We recently bought this bowl from a charity shop and are really struggling to identify it's origins! The shape is unusual, along with the yellow-gold banding. The pontil is deep (approx. 1.5cm) and ground with evident tool marks, and there are ground areas on the base too. It's a large piece - 20cm x 20cm x 25cm - and heavy. We have looked at of examples Monart, Nazeing, Welz and everything else on Google and are stumped, so any help identifying the maker would be very gratefully received!
