Now I’m not very knowledgeable on these.
I’ve only had a couple and there is so much
to know but from the ones I have had all
the reversing mechanism parts seem to be the
same except for the part circled. If you want
to disassemble yours press the pin out. If
you try to just knock it out often they will
expand before they are all the way out and
stop. Your 1922 should have the one with the
green paint on it in my photo.
A "Boathouse Repair" is one thats done without having tools or the skills to do it properly.
