I'm restoring an old Mossberg 352KB manufactured in the early to mid 60s. I'm having trouble figuring out how some of the parts fit together. Specifically the disconnecter, sear, safety and trigger assembly. The only thing I've been able to find is an exploded view of the gun. Does anyone know if specific instructions are available anywhere? If I can't figure it out I guess I'll just have to bag up all the parts and get a gunsmith to do it. I just hate to admit that I can't get er done.
