Doubt it is from WWII.
The extinguisher in your question was patented on Nov. 21, 1950 by Ignatius Nurkiewicz of Brooklyn New York.
Take a look at the second link. Is this the extinguisher you possess? Note the extinguisher was produced for the Air Force. The US Air Force did not become a separate branch of the military until 18 September 1947. WWII concluded in 1945.
STOP FIRE INC was the manufacturer.
