There seams to be some considerable stain. Was this bottle dug?
No matter really. I still stand by Clevevenger. Around 1934-40 and a special order or an end of day take home. That's not a bad thing, it makes it that much rarer.
A very nice bottle indeed.
If it is what I think the cup should definitely be glass.
Don't be put off that's it not an original BOOZ bottle (it's not). It's a great reproduction, be proud of it.
I did not think it was original...too many things don't fit. The cup is indeed glass, and it was made to look like smoke coming from the chimney...I love it, and have no intention of selling...just wanted to know a bit more about it, and possibly a value for insurance reasons.
If, and I say IF I'm right it may be one of a kind. That doesn't mean priceless. For insurance I'd get an appraisal from a good and accredited appraiser. If I were to compare it to a regular common Clevenger I'd guess in the $400 range. That's IF I'm right.
I don't know where you live but find a good appraiser in your area.
Still, wait for more opinions here first. They aren't done yet.
It appears to be made by the Dell Glass Co, Bridgeton, NJ in the 1940's from the original 1930's Clevenger Bros straight roof mold.
Dell made depression glassware and several of their decanters had shot glass stoppers.
These are pretty rare and in good condition(clean with no cracks, chips or repairs) would bring about $200.
