Hey I know this is a DEAD topic but I am about to defenestrate this bad boy.

Found it in a junk drawer with no key, and it was frozen up. I used some dry lubricant and beat it against the floor(figuratively) until it loosened up.
It's got 3 side-lock rounded pins perpinicular to the keyway, and very small short-travel pins at the bottom of the keyway. I have yet to crack this one, and it has a very nasty habit of grabbing my pick solid.

Currently my strategy that doesnt work is to feather torsion, slide over the 3 side pins, then rake while 'fanning' the wrench. I have had very little sucess getting more than 2 pins bound and solid, before the security side pins come out and grab my hook/diamond/rake. I have to use another pick to retract them to free my pick.
If anyone has any info on this lock I would be very grateful. Sorry for the cellphone pictures!
