A question for the experts -- Could someone have ordered the C&C with duals and the long running boards to upfit with a tow body or fire apparatus? Then maybe someone else got a hold of it and put the flat bed on it? 65 years is a long time to expect a truck to still be in its factory/original configuration -- Many things could have happened along that journey ...
Bottom line: Doesn't make sense to me to purposely put a flat bed over long running boards from new. More probable that the truck started out in a configuration that used the long running boards and then morphed into what it is now at some later point at the hands of someone who didn't have access to short boards or who didn't care.
