Are the internal parts the same, besides the actual muffler and differences in the knobs?
I guess what I am wanting to know, or see if anybody can photo it for me, are these parts:
the threaded rod that the full sized knob mounts on and how this attaches or activates the long arm.
edit: I found the patent number for the mute with the dial in Jay Scott's book; 3,134,288. I looked it up on the US Patent site and located some diagrams which are helping.
