2 extremely scarce M1 operating rods with major problems. 1. A very early -0 op rod that has the postwar alteration, 2. A unaltered -1 op rod. Here’s the bad news. Both operating rods have been cut approximately 1 1/2 inches short on the piston end. But wait there’s more. Both of them are missing the tab that rides in the slot on the receiver. Worth restoring.
