This is a 1960 International B-100. Produced for just two years for the 1959 and 1960 model years, the B-Series trucks were an update of the earlier A-series that went on sale in 1957. They shared the same cabs as the A-Series, but the front end styling changed to offer a more conventional grille and those stacked headlights you see here. Due to the short model run, these are not something you typically will see at your local cruise nights.

These trucks could be had with one of two different beds: a step side or a fleet side International marketed as the Bonus Load bed. This truck comes with the latter, and it is in good shape. To be honest, the fact that any of this truck exists 60 years after it rolled off the assembly line is a miracle, as these were utilitarian trucks that were used and abused and thrown away. We’re happy it’s still here!

Moving out back, you can see a better shot of that Bonus Load bed, which is in remarkable shape for the age, although it does appear to have some wood rails that could use some refreshing. And saddled right against that cab is the truck’s most unique feature: the propane tank.

Now, I’ve seen newer trucks with propane setups, but a 1960 International? I’m guessing it operates similar to a modern setup, where you typically start it on gasoline and switch over once it’s running, but I could be wrong. The most intriguing part of it is that it looks factory installed. Judging by the knobs on the tank, this looks like a manual affair. All we know is it’s really cool to see something like this on an old truck. If you know more about this setup, enlighten us in the comments section.

This truck’s bed even has a steel floor that still exists 60 years after it rolled off the assembly line. Color us impressed.

Moving inside, it’s typical old truck fare: a bench seat, steel everywhere, and just enough controls to get you down the road. Note how solid this thing is! The doors and door jambs look to be completely intact. That’s a good thing, since they only produced this thing for two years, so you’re probably on your own for sheet metal parts.

Like most old trucks, these mostly came in the three-pedal variety. This one even has a floor shifter. Nice.

Speaking of manual transmissions, these trucks could be had with either a three or four speed gearbox. This one was built with the latter, according to that finely worn shift pattern indicator on the dash.

These floors appear to have some heavy rust scale, but if I were a bettin’ man, I’d bet that they are more solid than they look. A date with the wire wheel and your favorite rust proofing paint would be a good start. If they do need to be replaced, it should be a relatively easy job, but you’re probably on your own with fabbing them up.

The instrument cluster is great on this old rig, Speedo, oil pressure, temp, and an ammeter gauges accompany that fuel gauge that just says “Propane” with no indicator. We love it. I guess you just drive it until it doesn’t drive anymore, since there doesn’t seem to be a propane tank indicator anywhere.

For “creature comforts”, you get three knobs for climate control and this possibly aftermarket radio from who knows when. Yup, that’s it, and that’s all you need.

Moving under the hood, we have a Black Diamond inline six with some extra bits attached to the fuel system for the propane setup. These trucks were available with three engines: the Black Diamond 220 I6, the Black Diamond 240 I6, and a 266ci V8. The seller says this one is a Black Diamond 240, good for around 140hp. And this one does run!

Here’s a look at the business side of the I6. That big pump-looking thing hanging in front of the propane-specific carb is part of the Ensign propane setup; this is the propane regulator. After doing a little research, it looks like Ensign made stuff mainly for farm implements, so seeing this rig on a road-going International truck is not too much of a stretch.  These have to be rare pieces, especially if they are truck-specific, and according to the seller, it still works. Incredible.

On the other side, you have some mismatched plug wires, your standard ignition stuff, and not much else. Again, it looks like it’s all there.

Underneath, things look more solid than most 10 year old trucks we see up here in the Rust Belt. These came with the venerable Dana 44 rear axle, which you can still get in some new trucks today and was installed in just about everything over the years. The seller does say that the braking system needs an overhaul, so add that to your to-do list.

Now this is cool: Take a close look at that door tag. It lists the VIN, GVW, and both “Certified Net HP” and “Certified Gross HP”. Looks like this one fell a little short of the 141hp rating, cranking out 131.6 HP at 3800 RPM. We wish all vehicles had a tag like this!

Do it. Do it for Hank Hill.
