I watched and listened to NKP 767 on CVSR on Saturday 9/24. I noticed that it had a yoke for a swinging bell but used an automatic bell ringer. I know that the NKP S-2's used swinging bells and the S-3's had the stationary bell with an air actuated ringer.
Question I have is.....can this bell be operated manually, that is, with a bell rope? Does this engine have a bell rope?
