Found some background at
JED.
Here is a quote from their
M-35 series page:
This 6x6 truck series was developed in response to Joint Army Navy Specification JAN-T-712, dated 17 December 1948. Reo completed preliminary work on this series truck by April 1949, and the requirements were finalized in May of the same year. Pre-production pilot models were quickly tested, and by 1950 production of these vehicles, then considered "interim" was in full swing.
Since the M-34 is the single tandem rears it very well could have been in Korea. I’ve seen photos of single tandem 2 1/2t and 1 1/2t before, just can’t vouch for the time or places.
It’s not like there is a history in the beginning of the TM’s. :-) LOL
