Nikkor HC 1:2 5cm LTM help needed

[Thomas Stellwag]

I bought a very clean and nice looking M39  Nikkor-HC 1:2 f =5cm Nippon Kogaku , no 719349. Just got it, but am a bit disappointed, as the seller didn´t mention that there is a resistance in the focus thread at ca. 3.2 feet.
Most probably it was regreased and not properly assembled. Any ideas from the vintage lens champions what to check or what to ignore?  F.e. my CV Snapshot Skopar has 3 similiar resintances, but here I know it is for finding the distance without looking to the meter scale. Is maybe this exisiting at 1m on the Nikkor? Non of my other Nikon LTM´s however has it, so I am wondering.

This LTM version allows to focus to 1.5 feet, but the rangefinder of the camera can only measure up to about 3.x feet (1m).  So, the click should be there to tell the user the closest limit that the rangefinder can function.

See the third paragraph from the bottom:

Akira, you saved my weekend - thanks a lot.
The other guy is a bit disapointed about your support. He wanted, that I send it back. He got a Leica III today and wouldn´t have sold the lens (for this price), if he knew that before.
It is a like new lens, which I add to my Nikon LTM´s  3.5/28, 1.4/50, 2.0/85 and 2.5/105.

Thomas, I'm glad to be of some help, at least for you.
