Those shiny pins on either side of the keyway are factory hardened steel pins to make drilling harder.
The lock cylinder is exclusive to the 747 and 748 series locks. Would love to get another cylinder for the lock (and put it in a 748 lock in my collection), but they are a pain to get.
Therefore, have no intention of drilling that lock cylinder. Plus, I'd rather keep the lock original.
Picking is difficult due to the strength of the return spring. By the time I have enough tension to bind the pins, I can hardly feel anything. How strong is the return spring? The only tension wrench I have strong enough to even turn the plug enough to bind the pins is the thicker Peterson Pry Bar.
