What are these other pins in my Medeco biaxial?
And here's what it looks like disassembled:
No, I didn't pick it. I popped the cap off the top and dumped all the pins/springs. I was sloppy about it and chambers 1-5 all spilled and got mixed up, so I'm not sure if this is exactly how the pin stacks were originally, but that is besides the point. This is my first time dissecting a Medeco, and I am curious about the purpose of the pins/springs that I've highlighted here. Here is a close-up of the pin in the 7th chamber, with pin and spring detached:
My best guesses are that this pin is either for key control or to make the core key-retaining. I have no good guesses about what the other pin/spring is for however:
Rather than inside the core, this is located on the back of the bible, here:
I haven't seen pins in such odd places before. So, what are they for?
