thank you John

The rim on the pink one you linked to is very similar to mine as well as the claw trail. I feel they must have come from the same source. Now we just need to know the source. I do wonder if they are from somewhere else in Italy, not Murano, rather than Chinese. Mine is relatively heavy and has little wear on the base really. It has good features, it's quite sophisticated and not at all coarse, my only reservation is that base.
