Hi there, I Hope someone can ID this large and heavy white porcelain dish (14 1/3" x 18 1/2" x 1 2/3" - - 36,5 x 47,0 x 4,0 cm) I've found in the loft of my grandfather's house. It has on the edge a flag logo with blue H and red A letter in it. It is certainly over 70 years old, may be even ww1 time, Sofar no logo like this I've found on the web. To identify it may be helpfull information the item is located in Triest (Trieste / Trst), actually Italy, bordering on Rep. of Slovenia, but at ww1 time the town was a harbour of the Austro Hungarian empire. Thanks for your time and care
