I just got a hold of this 9N from my father in law. It sat for a very long time. When I got it home I was able to turn over the engine with a hand crank from a 72 Land Rover I own. I'll try to keep it pithy. My in law said he got it from a guy who painted it Blue.
I want to restore it to all Gray one day. It had lots of antifreeze so no cracked block. The problems: The electrical is original and wires are exposed so I have to fix that before I try to add power. The generator is frozen tight. The starter works with a 12volt battery hooked up directly and I was able to see the oil pressure gauge working so getting oil pressure. The rear wheels are rusty but hold air. The cylinder head nuts are rusty beyond recognition.
Anyway, as you see I can go on and on. I hope to be able to get her running again with the help from here. Question: How do the valve guides get oil for lubrication on this flat head engine? Parts missing: Radiator cap, Air tube from carburetor to air box.
