The Vin cruncher didn't give accurate results because you entered the letter 'O' as a Zero.. with the VIN corrected, 21OS042402 it shows as a 1946 Interm series 1.5 ton with a 160" WB.
My two ton has the standard 4 speed tranny with the reverse lockout lever, and the same shift pattern as my 1/2 ton.
I think the two tons came stock with the vac brake boost assist on the passenger side of the frame, oppisate the master cylinder.
The 2 ton '50 I had was a four speed.. reverse was in the same spot, but there wasn't a lockout.. you just gave it a push and it went.. like there was a spring in there to give a little resistance to keep you from accidently going into reverse.. if that makes any sence.
So my guess is that the truck you're looking at has had the tranny updated with something far newer than a '50.
