I need help from the experts regarding this nice ashtray with remains of the classic silver-on-yellow-background Bohemia label.
Light blue glass with internal dark blue spiral, 15.5 cm long, 8.5 cm wide.
Sort of wedge shaped -- very similar to my Stahlikova/Veliskova ashtray
(especially to Jindrich's example further down in that thread).
The spiral pattern plus colours are a match to the Stahlikova vase PN 5927 -- here is a pic
in Dusan's gallery.
BUT -- I cannot find it in the pattern books...
There is one ashtray with a blue spiral by Jirsakova (PN 6044), but the drawing shows only the top view, so it could look totally different in reality.
If not Skrdlovice -- which other makers are possible?
