I had several Yale euro profile cylinders with that logo. I didn't realize they might be anything fancy so I just put them in with my box of practice locks that I use whenever I go to any conventions, meetups, etc. to put out on the table and let people pick them. I don't recall anyone mentioning anything about them being particularly difficult to pick. Makes me wonder whether they had the anti bump/pick/drill features that are listed on your Yale web link.
I don't even know if I still have any of them. At most lockpicking meets I usually tend to give away a few locks and picks to novice pickers who don't have many materials to work with. Sometimes have a few items lost or stolen, or ruined, so I periodically buy bulk lots of locks off eBay to replenish the supply.
Thanks for your post and link. I'll have to sort through those practice locks and see if I still have any remaining so I can gut them and see if they have anything special inside.
