Hello, I have an ashtray with the same rose in the bottom, Its about 8 inches across and very heavy. It too has a tinge to the glass, its in the roof somewhere, I'll find it if anyone wants to see a photo.I picked it up on a car boot a few months ago for 50p, I don't smoke but I loved the rose pattern in the base, seems nicely made. Been meaning to find out who made it but it got packed away!!! Cheers cheryl.
