Hello Dave,
From what you have described, you have found RibbonBridge Transporters built on a M812 chassis. I don't know the M number of the complete transporter. (The 50's era bridge truck commonly called a M139 really isn't....M139 is a cab and chassis, M328 is the truck, stake, bridge transporter, for example...the 800 series equivelent of the M328 is M821.) Fairly interesting truck, especially with the big unfolding bridge bay mounted on it. Here is more info from a DOD paper:

Hope this helps,
