Dave,
I finally made my way to the back of the garage where the National 9 Pull was stored and it does have a complete mech. I sent you a PM. Here are the pictures.
Can somebody help me with disassembly?
I have never pulled one of these apart and don't want to remove the wrong screw and find a pile of parts and springs on the floor. Just point me to the correct screws/bolts and I think I can manage!
Tim
