No, unfortunately it isnt mine!
I just browse ebay motors sometimes looking for these out of interest.
However the local fire department ran a 1943 GMC CCKW untill 2005 as a brush truck. Apparently was bought out of a crate after the war and assembled! I'll see if I can dredge up a picture of it, as its now a reserve truck for the state (who I work for) at the local state forest. Although I fear the end may be coming for it soon, the breaks are apparently gone now....
