I do know that the "N" designates four valves. I have one. Well two, but one running. And it is the 5-1/8" bore, 743 ci.

Here's our family tree - hopefully this will help clarify things a bit...or muddy the waters it could go either way

The HB is a revision to the model H and it happened very early on in the life of the H. The very early H (1932-1935) had babbit bearings, different diameter crank journals, different pistons, 4 7/8" bore 6" stroke. In 1935, the revision B was released that switched to modern serviceable bearings, larger crank journals, and an increased rating.

The NH came out in 1944, with the 4-valve head, new block, new other stuff, 5 1/8" bore 6" stroke. To confuse everyone, we also bored the H to 5 1/8 and called it the HR.

In 1957 we bored the engine again to 5 1/2" bore 6" stroke and called in the NTC855, along with other upgrades. The H was obsoleted, and the NH was bored to 5 1/2".

1970-75 we made the N-927, which had a 5 1/2" bore 6 1/2" stroke.

Then finally in 1990 we updated the engine one last time to the N14.

And all this doesn't include all the variations for supercharged, turbocharged, horizonal, or V versions of the H family.

The disc on the vertical shaft is definitely for throttle control.

Not that its of any help, but the extra air filter may have been a Cummins option, possibly Donaldson brand. I know I've seen it on a number of industrial engines including the larger Model L engines.
