Under the hood is another Marmon-Herrington upgrade. They swapped the stock Ford 221ci Flathead V-8 and replaced it with a 100-horse 99A Mercury V-8 that measured 239ci. On the Merc motor they also mounted a six-blade fan along with a matching fan shroud. The more potent flat motor is hooked to a '40 Ford four-speed truck trans fitted with a heavy-duty 11-inch clutch. All this churns through the predecessor to what would soon become the transfer case, called a compensator, which seems to be a fairly complex unit for its time. The compensator would sense extra strain on the driveline and engage the front axle-the analog version of what many vehicles use today-and to disengage four-wheel-drive you would simply come to a stop

Save for the "blacksmith" rear bumper installed in '51 and the Marmon-Herrington conversion, the '40 is unchanged and unrestored from Ford's intentions. Inside the cab it looks to be straight out of a time capsule and even houses the optional gas heater that kept Mr. Ficken warm while delivering the mail, and the original 6.50-16 spare tire is still mounted to the bedside. Connie even has the original letter from The All-Wheel-Drive Company telling all parties the details of the sale and letting them know Marmon-Herrington would wire them when the truck was finished and send a check for $785.97, which was even 15 percent off the regular price.

We haven't been able to find out much on prewar 1/2-ton Marmon-Harrington trucks, except for the fact that they are more scarce than hen's teeth, and to find another in this preserved condition would be next to impossible. But that doesn't stop Connie from taking his grandkids out fishing in it during the summer-nice catch!
