Clutch and drive side.

Looks like mostly New Departure parts, with a different transfer spring (E-12), in addition to the 3-lug (tab) sprocket driver with snap-on lock-ring.
The diagram also suggests that the drive clutch (E-3) and the brake clutch (E-6) are also not individually interchangeable, (replaced as a set?).

The clutch design looks to attach the drive clutch to the brake clutch transversely, pulling the brake clutch away from the disks with the drive clutch.
Perhaps it was an improvement?

@DJF ""I would like to use the below brake arm but need to know what year and hub it is for. Any ideas to that?""

I was just going through this thread and found this early ND C hub, 1918-ish?.. that may have preceded the large production of them through 1933 as they say. From page 35 post #349

Interesting hub! Is it stamped Model C on the shell?
Certainly a distinct version of the ND coaster arm, Model A characteristics without the distinct toothed interface where the arm meets the race. Does the arm mount in the traditional Model C fashion?

Funky missing link!

Below is another picture of the parts of the hub (found in Europe) from post 349.

The unique lever arm, with the deep square hole, would fit on a special disc support sleeve (separate from fixed cone).
That brake also used special discs, with three internal tabs to interface with the disc support sleeve, unlike the model D; (O.P. indicated that he bought replacement discs somehow).
Also, 5/16” bearings shown at the small adjusting cone (like the model A).

Yes, and fewer disks?~ A more complicated axle keying strategy for 1/2 the friction discs than the next gen C and then D hub. Axle to brake arm is very different as well. I wonder if the small holes drilled into the discs were for oil/lube movement?

This is the first patent I could find for a design including disk brakes ("friction-disk type") by Victor Page' assinged to New Departure Mfg. It is was applied for in 1912 and granted in 1917. This fits with the 1916-1918 timing for the Pegot bike the hub above came from.

Anyone know of an earlier hub that used friction disks?

He builds this patent "on top of" the Rockwell 745,524 New Departure Model-A patent from 1903.
