OWD, to my untrained eyes, those lock patterns actually look very similar with the pins in what I would describe as a "flying seagull" configuration (think how a small child draws a seagull flying in the distance - literally two arches converging in the middle).
Toby, thank you for that excellent and very detailed explanation. I think I have a much firmer grasp on the mechanics of the lock as a result. I guess the takeaway is that the only way to definitively know what the internal mechanism is would be to open it up!
