Octa-Gane Vintage Water Injection System Tank RARE Los Angeles U.S.A. - $45 (Ankeny)

I have for sale a tank and mounting brackets for a vintage Octa-Gane water injection system.
Several different companies made these types of injection systems from the 1920s/1930s through the 1960s.
The gimmick was that this system was supposed to improve mileage and performance as well as eliminate pinging, although there is some disagreement as to whether or not they actually worked.
Octa-Gane made 2 different types of system.
One was just water injection.
I believe the other was some combination of water and alcohol.
This tank includes mounting brackets.
The inside of the tank looks pretty good.
Unfortunately, someone dented the back either in storage or "making it fit".
This tank is about 12" wide and 6" in diameter.
$45 firm Thanks
