Awesome. The early cars are so nice looking. I'd love to have any of them.
Go for it. You might get a smokin deal !!

Really. I am amazed. I believe I read a road test of the one (in the MBCCA?) that is in the mb museum in Stuttgart and I thought they said it was the only surviving one.

Perhaps I am all wet or it was actually a different model. I believe they blew the motor on the museum car in the course of driving it around.

I'd love a 170 to piddle around with.

Does anyone know what was the first diesel model Mercedes made? Seem like the 170D has got to be pretty close.

The W138-260D is not that rare. Production total was 1967, but I've seen a few over the years. It was the first passenger car diesel in the world. It dates from 1936.:

At the MB Museum in Stuttgart, a 260D Pullman



At the Technik Museum in Spires (Germany):



At the Fritz B. Busch car museum in Wolfegg, Germany



A 260D at the oldtimer fair MECC in Maastricht, Netherlands (2011):



And the front, with a 1,000,000 km badge



And a 260D-engine (OM138). 45HP at 3000 rpm in the Auto & Technik Museum in Sinsheim, Germany:

Dang, man, didn't you watch the video I posted?

Totally missed it. Watched it now though. I quick wiki search answered my question too. Pretty cool. I want one of these!
How cool would it be to be an owner of one of the worlds first production diesel cars.

Looking at the picture Govert posted, the injector has an integral glow plug?

The glow plugs are below the injectors I think, but they are difficult to see.

The line running between the injectors is the return line.

The basic design of the engine is similar to the OM61X.

There is a pic or two of a faded blue one from portland here on the forum from a few yrs back that a member owns.

I thought the copper loops were connectors. The return lines lead to a fitting over the flywheel. I don't see how the return lines are attached to the injectors. Looks like the copper things are just supports. The glow plugs must be hidden from view by that block long injector line clamp.

You are overdue for some better luck, maybe this will be your payback.

That's one of the ones that was for sale, the other was black and in better shape. I probably should have at least driven up there and looked at them so I could say I've seen one in person.

I have seen these early MB diesels referred to as side valve or flathead engines a number of times on the forum, in fact, one of the posts on the first page of this thread calls them sidevalve engines. They are not sidevalves or flatheads, they are pushrod OHV engines. I don't believe there has ever been a successful side valve diesel, the extra combustion chamber size required to accomodate the valve-in-block arrangement makes a high compression ratio difficult to achieve.
