May I add most unsatisfactory - I just tried the suggested route and it lead nowhere.
In any case, there are a few new things to add.
First of all, without room for mistakes, a blue bowl with three lion prunts and gold in the cristallo stand, rim and prunts. On the underside the unphotographable remnants of a scalloped gold foil sticker where MA, I and IT can still be seen. MADE IN ITALY - a generic label, which maybe someone can date?
Second, from the same source as the blue bowl, two red salts with clear trim and gold powder. I believe these are quite recognisable. My suggestion is Barovier & Toso. Can anyone confirm this?
