I have a 1927 Smith that has a rotary joint check mechanisim that among other things controls the extractor. There's a spring inside this rotary joint check that is broken. I need to remove this rotary device in order to get at the spring and replace it. The extractor comes out easy enough with the removal of one set screw.
Pictures of this rotary joint check are attached. I need some experienced advice from any 'smithys' out there on how to remove this rotary joint check to get at the spring.
