Sparklets Ltd London soda syphon c.1930s - red fill line, complete with bulb cap

An original Sparklets soda syphon from the interwar years - Sparklets of London invented the charger-bulb syphon, and this is the classic: glass bottle in woven wire mesh, "Do Not Fill Above Red Line - Made in England" engraved on the collar (red line still visible through the mesh), spout stamped Sparklets Ltd Makers London, and the original charger cap on its chain stamped "Use One Bulb Only". The head unscrews cleanly and the internal syphon tube is present - completely complete, which after ninety-odd years is the hard part. Gatsby-era engineering that still looks the business on a drinks cart. Sold as a display and barware piece.
