My first try on the forum. I have found a mark on several pieces I have that I can not find the maker or any info on. It is a W with a line on each side -W-. Thanks, I appreciate any help I can get.
Have seen it several times before, on mid 20th century items similar to your cigarette urn and ashtray - might even have a piece somewhere, but honestly can't recall if I've ever seen a firm attribution...
