always seems a bit 'tacky' collecting ash trays - but was offered a few on the cheap today. Did you know for example that the main Cancer Charity Shop (understandably I suppose) are not permitted to sell these items. Am thinking this one is Neodymium, but didn't realize there was a code (or whatever) on the underside until this evening - as shown in the pic., which I think reads B 2544, and the fours certainly look continental in their style. The piece has a lot of wear on both the top and bottom, but I hesitate to put a date on it. Diameter is about 145 cms, and very free form in its looks. Wud grateful for anyone's advice on the on the code and age please, and thanks for looking. Cheers Paul S.
