Picked up a couple new locks to work on yesterday and today:
First up was a Master No. 532

Not sure about any security pins, but the warding made it a little tricky to get my pick in there.
Next up was an American 1105:

The guy at the store told me this cylinder has mushroom pins, but I honestly couldn't tell. I might return it for another lock with a different key code(?), as this one is pretty much the same all the way across, with the exception of a 7 thrown in.
I also busted out one of my BEST cores to give it a try since I've been practicing more. Apologies for crappy photo:

From the previous ones I have disassembled, there are no security pins, just the small wafers used for multiple sheer lines.
I've got a couple more locks I have yet to unpackage. One of which is a Stanley Professional Grade lock which states is has a "special anti-pick pin that resists picking attacks". That too has some heavy warding in the keyway, but I'm pretty confident I can get it open with a little time.
