Found this on the Norton Owners Club site.

FAQ - Roadholder fork dimensions
Although many parts of the various versions of the Roadholder fork are interchangeable, one major difference between them, and a constant cause of incorrect sourcing, is the fork stanchion length:-

TYPE   FITTED TO   LENGTH
 Manx                20.375"
 Short Roadholder    21.843"
 Long Roadholder    23.312"
 Commando        23.161"

Your stanchions, if correctly measured, are 20.4724".   20.375" equates to 517.525mm

I have been unable to read the numbers on the underside of the top yoke. If I had the number I could ask the question on the NOC forum for you.

The bottom yoke is the same as my RE Interceptor Series 2 and also on Matchless G15 model

So as far as I can make out the top yoke has N4 ? T777 stamped in it ,and the bottom yoke N4 T555 , and the two parts line up to each other when I insert the fork stanchions .
