Vintage bistro siphon sparklets english glass and tin

English siphon (it is signed on the cap: "sparklets ltd makers london") It opens perfectly. Very thick transparent glass in perfect summer and tin type metal or openwork silver metal, like a mesh. Some defects of its age (mid-20th century) on the metal part. Especially on the cap, it is destitute. We perceive a little moisture inside: I dry it as much as possible before the sale. Other photos on request. Nice decorative object! Mid-century.
