Today it's a cool item I picked up this week.
It's a stainless steel 1961 General Soda-Acid Fire Extinguisher and looks to be all complete.
It's a really cool item that makes a statement in any room
Dated 1961 although I'm sure it was used up through the 70's
Here's a close up of the nozzle.
You open it up and inside is a suspended glass ball with a lead topper.
Inside the glass you'd put sulfuric Acid and the lead topper would open once you tipped it upside down.
Filled with a mixture of water and sodium bicarbonate. Once they mixed Co2 would be produced and out shot the water through the hose.
Model SS-15b... I have know idea about the model numbers.
It's just a cool piece that looks great to my eye. It's vintage (early 60's) and has a real "Working Man" feel to me. It's vintage gear for guys!
