John, Nick, thanks for the input.
Looks like the value of these old trucks is a little less than I thought. My 54' looks to be in a bit better condition than Nick's trucks and maybe a little better than John's. It is difficult to tell from a few photos, but I'm now thinking that it would be a $3500+ truck on this website. Has the slow economy "softened up" the old truck market quite a bit? I haven't really kept up with it. The reason that I ask is because I've had "standing offers" in the past that were considerably more than $3500! (Maybe time to get the old address book out.)
Thanks again for all the good info! I'll keep snoopin'!
Robert
