Help identifing cylinder

Hi people.

I was recently given a cylinder from a padlock, unfortunately no key.

I haven’t seen one of these before. The first thing I noticed was the shape of the bible then the pin loading holes (ports??).

The pins are set at an angle and there is a rail (?) along the top of the key way (pic 4).

Could anyone here identify it and/or point me to more information. Would also like to see a pic of a key.

From the small amount of time that I have spent on it, I think it will be a “fun” pick.

Thanking you in advance.

Very cool. Scary to look at. I need a shot at one of those.

Definitely a V7... not that hard to pick, though they do have pretty good tolerances IIRC. See my video #50 for a pick and gut if you are interested. My understanding is that this angled pin format was employed to defeat lock bumping.

It was also a benefit in terms of Lockwood wishing to provide a restricted key design. A variety of broaches were employed by Lockwood (and the MLAA) under design protection. The seventh pin provided more possibilities for keying and the broaching systems allowed multi broaching to expand systems further.

Unlike 6 pin inline systems with restricted broaches, the key design and angled pins made it a lot more difficult to produce keys outside of the authorized dealer network. With 6 pin inline systems, you can simply mill/file a similar blank to fit most restricted profiles.

McG.

The tail piece has a pin in one of the lugs.

I discovered it when it fell out onto the floor. Can't see what it does. Maybe if I had the pad lock.

i think it might change it from key retaining to non-key retaining. maybe... dunno
