Hi Forum
Besides the orbital clock bushing I have noticed several of my Jennings have an additional pieces added on to the MOB
Any idea why this was done?
Was this original or done by operators?
Thanks
John

That was done to change the timing a little each pull. Probably factory or operated installed.

Hi Forum
I degreased and freed up the orbital bushing, sadly with age it is too free and the first reel only goes a few symbols
I am going to try to seize up the bushing so the fat part stays facing the MOB
