Item BE4: This round, 2 1/2" high x 2" wide x 3/4" thick squeeze perfume bottle is fascinating, to say the least! I have searched and searched and found not one like it! I took it to our local antiques dealer and he identified it somewhat by the patent on the back, as being from 1940's - 1950's.
It is made of shinny brass, embossed/incised with a typical Roman zig-zag design with a group of flowers in the very center of front, which pushes in (part of the squeeze process). The back has a black Bakelite 'button' in the center that he says you push/squeeze at the same time, to eject the spray, after having removed/unscrewed the lid. I have not disassembled it to investigate further, but am going on the word of the antiques dealer. He says it is refillable. If filled, it will hold about 1oz. The scent of past perfume still lingers at the top.
The back is marked: Brevetto (means ‘Patent’) No. 6297-3221 - Made in Italy. Near the top-back is a logo that is a shield type design with what partially appears to a bird.
