Hi again (from Ireland) ,
The closest I can get is Blenko with this ashtray or bowl ?
It is heavy at aroung 1kg and measures 6 1/4" long x 2 1/2" high
Clear glass with green and wear to flat base .
Not sure it would be great as an ashtray so maybe a bowl ? 1950's or 60's ?
Many thanks once again , Dave.
