I am not doubting what you are telling me, as I believe the Americans didn't enter the war until Dec, 1941. What I wonder though is, from what I do know; The 741 was developed in 1941 and the 344 was a 1944 military chief. So why do we have an 841 and not an 842, if the bike was a 1942 model?
I am not trying to be smart. I have just had trouble finding any accurate info on the bikes. Most of what I find is the same old rhetoric about 841 and XA developed and pushed out by the arrival of Jeep, but bugger all on dates or anything else. If anyone knows if any good info sources out there, I would love to know.
