Interesting. So the Atlas Scrambler/early G15 and N15 used Matchless Teledraulic dampers in Norton Roadholder forks??

Yes, the "Atlas Scrambler" had Teledraulic scrambler type dampers, external main springs and possibly other alterations.

I have a set of dampers from an N15 (year unknown) and they are identical to Commando except the damper tubes are 11" rather than 9 1/8".

These are internals of the 1966 type street scrambler forks, which were identical to the contemporary Matchless heavyweight roadster forks.

I do not know but NO extensions were on my 2 sets of Scrambler off road forks.

An informative post is from Bill, here:

His post says stanchions for offroad forks are 02-8048 and road forks stanchions are 02-2890.
Anyone know the actual difference between these stanchions? Can they be made to interchange?
Waldridge sells 02-2890 only.

The exchange with Ron L. was about the "Atlas Scrambler", not the P11.
The forks on these bikes differ on many points and should be discussed separately.

As for 02-8048 and 02-2890, these are damper tubes, NOT stanchions. 02-8048 is the scrambler type used on G80CS and the P11 (also some P11A's).
It has been remanufactured by A.N.

02-2890 is the roadster damper tube which remained unchanged since introduction of the 1-1/4" forks in 1955. It was fitted to later P11A and P11 Ranger models.

For fast road driving using a bike which has Teledraulic forks fitted, a different type of damper was specified, p/n 02-2821. It was standard fitting on the G12CSR model.

Thus, there are 3 different dampers available for the 1-1/4" Teledraulic forks. Without further investigation I think size of orifices is what separates them.

Most of those parts will be fine when you take the forks apart. All you will really need are the seals and bushes. I'd go with the bronze. Things like fiber washers can be sourced at your local hardware store.

With the 56 balls: A greased cardboard toilet paper tube fits the headstock perfectly and will keep the balls from rolling down into the frame tubes when you replace them. I left it in for future times. This was on a '66 G80CS which has the Teledraulic forks. There is a nice tool to pull the fork tubes up into the yoke. I sure needed it because the external springs prevent grabbing the fork tubes to push them up.
