The allusive DEMONE K-valve assembly.
The name is pronounced DEMON and the reason there is an E at the end of company name is because
of the two founding owners, Robert Dempster, and Albert O'Neil. They chose to use the first three letters
of each of their last names DEM and ONE, but called the company DEMON (hence the little devil logo).
DETAILS;
Tank Valve, original and stamped with the DEMONE symbol (little devil).
display items in picture with valve are NOT part of the auction, (only the valve)
If you are a collector that also seeks orginal Demone catalog/literature then stay tuned.
I will also be listing the DEMONE MK-2 regulator on a very rare ALL original 72 cu ft. tank / pack assy. in the near future.
