Antique/Vintage Sonimex Vacuum or Siphon Coffee Maker. Apothecary/Chemistry/Laboratory Stand with Burner.
Neat looking adjustable stand. Glass is intact. Has original cork sleeve. Burner may or may not be original to this but was was kept with this for 70 years or so and can still be used with this.
For years, I thought this might have been specifically for Apothecary or Chemistry but found one day that this was used to make coffee.
