I am looking for information on how to completely disassemble the J.C. Higgins Model 30. The Action Rod is broken and I need to remove it to replace it or weld it. But I can’t figure out to how to remove it without damaging anything. The trigger group and bolt pop right out. This model has the left side action rod knob and the right side ejection. Made Est. 1950-1952 . Any info would be appreciated.
