I've found a few of these ashtrays, all about 7" high and all bought in Canada. The glass usually has a yellow tinge, though one has a blue sommerso drop. I thought originally they could be Chalet, but, according to what I've read, Chalet was usually marked and none of these is. I added the Harrtil (also bought in Canada) because it made me think that they might be Czech. The glass feels and looks the same. I've included the bottom on one as they all have the same bottom. Please ignore the label as I put it there. Any help appreciated.
