It looks like its all there, what did Bubba do?
According to what I read in my copy of Numrich Gun parts catalog #24
Only six civilian sporters were sold in the USA by 1939 that had featured sporter stocks.
In 1940 the Dutch Govt purchased huge quantites of the Johnson Model 1941 (its called Model 1941 even back in 1940),
the order being diverted to the Dutch East Indies when Holland fell to the Germans.
In 1940 The Dutch furnished the steel for the barrels and shipped to Johnson in the USA, U.S. customs's duty had been paid on the steel, a draw back on the duty could be claimed, but under the war time conditions and confusion, this drawback was postphoned, after the war a interesting situation of a virtually defunct company that had a sizeable asset in a duty drawback claim on steel imported in 1940.
Some time in the 1950's 16k were sold by the Dutch Govt to a Canadian arms firm that refurbed them and sold them as sporters. M1941 Johnson rifle - Wikipedia, the free encyclopedia Numrich Gun Parts Corp. - The World's Largest Supplier of Firearms Parts and Accessories
