I'm not so good when it comes to ashtrays except for the special Fratelli Toso ones. If I remember right, Formia made an ashtray similar. Alas, they have upgraded their site and I can't find a thing on it anymore. I also believe there was a similar Czech design. I looked a bit on Jindrich's site, but couldn't find anything right away. I'll search my own files a bit more to see if I can find the Murano version of the ashtray.
