Need Help Identifying This Lock! (pictures included)

[patv]

Hey guys,
Picked up this lock today. Did some searching on it, but all that comes up is people discussing using diamond picks.
I'm curious as to why it needs to be turned three times to be fully locked. Is this just so the door itself is harder to knock down, as the bolt is further inside the wall?
Any information would be great.
Thanks!

Gah, messed up the third image.
Nothing special, but I'll add it for the sake of being complete.

Looks like it needs 3 turns to extend the deadbolt fully. Made in China. Try looking here. www.made-in-china.com. Pages of them!

Is that done just to have the deadbolt be of a longer length? Or is there another reason why it would be done?
Thanks

Yes, and since the rotational distance only translates to so much linear distance, you have to keep turning the key until the bolt is fully extended. Has nothing to do with picking prevention or anything of that sort.

Awesome, thanks. I thought that's what it was, but I had heard of some locks that if picked, the pins drop back down every quarter turn, thus forcing you to pick it four times, so I wasn't sure if this was some system like that or not.

That sounds like a Papaiz cruciform lock, or an ACE (or any other brand) tubular lock, although the turbular lock would be more like every x degrees not just 4 times.

Glad we could help,

Intentional or not, you have to pick it 3 times. (plus possible 180 degrees jam)
It does not make it harder, but it will take 3 times as long to pick it.
I would think this is a security feature, I bet they could have made the gears so that you need only one rotation.

Wouldn't it be possible to over-come that with a plug spinner?

Ah you're right. Just picked it once, got the deadbolt into the first position and then it stopped.
Here comes round two!

You actually only have to pick it once. Use a plug spinner for the additional rotations past the shearline.
