Mystery Manifold

[Bruce P]

Hello everyone. My neighbor was cleaning out a shed and found these parts. The manifold ( PN 4F7087)looks like it would fit on a D318 but it's the heat exchanger (PN 4F7486) that has me puzzled. I haven't seen any 9Us around with this setup so is it off a road grader? We are along way from the ocean so I doubt if it's marine but I don't know. Here are some pics, any thoughts.

Whoops
Didn't all go through, here's the rest. The starting engine exhaust appears to fit with the rest of it. Bruce

That's the early D318 exhaust manifold that had the heat exchanger in the intake pipe you show above it. Later models went to the tube in the exhaust manifold.

Well that settels that. All this stuff was given to me and I don't need it, so if anyone out there is putting an early 318 back to stock, you're welcome to it. Just let me know.

Those look like items off a D6 'u' series, including the pony motor exhaust manifold and electric starter.
