a friend of mine is doing some research and has asked me for help:
here's his request:
"...I am trying to find photos of the big WW2 7-1/2 ton 6x6's built by Federal, Reo, Sterling, Biederman, and even a few by Corbitt. Most of these were C-2 wreckers and F-1 tractors, but some were outfitted as Cardox crash trucks also. I am particularly interested in Reo wreckers, both the 7-1/2 and 10 ton. I've attached a few photos so you can see the what the models I am after look like...."
Pic's below, any assistance appreciated with links to sites and old threads..
