Dave, I was actually talking about the manual focus predecessor of the lens you bought 
.... That AF Micro-Nikkor 55mm f2.8 you found/bought was the short lived AF version of that lens (the friction thing gave that away). It is a very good lens optically, and pretty rare as it was not a big seller in its time, due to the quality of the 1st Nikkor AF SLRs (which were not selling in huge numbers yet) and the unusual design of the lens with a small focus ring.
Differences with the MF version: The MF version has greet MF action with a well designed focus ring, the AF one you have goes to 1:1 all by itself as it extends more with a double tube (which is why you have not read about the PK-13 extension ring).
You bought yourself a rare gem there! I had the MF version for a short while, but gave it to a friend because she might use it more than me, as I also have a dear to me micro-Nikkor 55mm f3.5 from the 60'-70's. Enjoy your nice little macro, it has lovely optics.
