Don't know what company converted my 58 F100 4x4 or when, and looking for tips to help identify if it is a Marmon-Herrington, Napco or other.

No apparent tags on the truck. Front axle is an open knuckle D 44.
Any help will be greatly appreciated.

There should be an I.D. Plate in evidence on one of the Door Jams or evidence of where it had been installed by one of the afore mentioned Co.'s.

 

An open knuckle front-end suggests Backyard Bob converted it. I don't believe any domestic front driving axles had open knuckles until the late sixties, certainly not Dana/Spicers. Check the transfer case, see if there's a Dana/Spicer or NP (203, or 205) tag on it, does it look like a modern case? Is it a divorce mount, if not, then most likely Bob has his fingerprints on it. Another giveaway is the appearance of any modifications, uniformity of fasteners, brackets, etc. Anything looking like it was fabbed using a gas-axe, again, is credited to Bob. I'm not trying to be a smartarse, but if was a M-H, or Napco conversion, all brackets, crossmembers, and fasteners would be top-notch. Granted, everything else may check out, leaving open the possibility the original front end pooped and was replaced with a modern piece.

 

I'll ditto 1952henry's comments, and add that there'd be signs of missing badges or data plates if it was a factory or dealer installation. You'll find holes in the cab with the shadows of missing plates, or shadows/holes in the hood or front fenders. To see what a Marmon-Herrington of that era would have looked like (not necessarily the body, just the badges, wheels, etc) check Ebay posting #4588041635. Stu
