Just curious about something

Does anyone know much about these "Marmon Herrington" 4wd conversions? I've only really just noticed it looking at our old 48' ford f5 grain truck, from the tiny bits of research I've done, they're not super common and I'm just curious what something like this might be worth (I know, kinda hard to put a price on a ratty old farm truck), currently no plans for the truck but that might change in future

Also here's a bonus pic of my project truck I'm working on currently with my dad! (47' mercury (originally a 1.5 ton) sitting on an 04' Chevy colorado frame powered by a (very slightly built) 6.0 ls)
