I recently purchased a beautiful 1960 Single Six. The only concern I noticed was that instead of the nice click-click-click-click on cocking, I was getting an uneven click-clickclick-click. The cylinder latch seemed to be lifting too soon. An inspection of parts revealed nothing- or so I thought. So, after perusing Kuhnhausen, I ordered a new hammer plunger and a new cylinder latch ( actually 2 of each in case).
Comparing the new cylinder latch with the old told the story. The old one was very rough, and had a filed spot where the hammer plunger rides. The new one was smooth, a bit longer at the plunger contact point, and a bit wider.
I swapped the cylinder latch for the new one and reassembled. The latch now falls into the lead when it should. Lockup is a bit tighter too. Timing looks spot on. Success!
I have done plenty of work on New Models- but this is my first job on an Old Model. I really appreciate the workings of the Old Models over the New.
