I'm posting this for a friend and wondered if anyone could shed any further thoughts, as to age, country and intend use. Please excuse the photo quality.
The bottle is mold-blown and measures 24cms tall and is covered in metal filigree work with a central double headed eagle motif.
I suspect, Germany is a likely contender given the symbolism, however, I understand that this motif, was also fairly widely used and could also point in other directions such as Russia, Turkey, North Africa and also further afield.
Although, the item has some age, at present I would guess it could date possibly any time between the 20s-50s..?
All thoughts welcome.
