Old lever lock I.D. Opening help needed

[awol70]

ok, here is an old lever lock,in the second stage of cleaning.
during scrubbing decades and decades of gunk and crud from the surface of this lock,i uncovered some markings,evidently a stamp.
tiny letters :"QW WOCK" ( or something close to that..) stamped on the shackle
??
i dont get it.
can anyone identify this lettering?
anyone know the type?
i inserted a turning wire,and found what i think to be three levers.
how do i tension this lock?
note:
i posted pics of this lock once before,when it was very dirty...
the letters were not visible.

It sort of depends on if it's a flat lever key or a barrel key. I have a few flat keyed lever locks, and the best way to tension them that I've found is simply to pull up on the shackle while picking. For barrel keys, I'm not as sure but I think the same method works, though I have seen people put some sort of tensioner down the shackle hole on the left side. I'm not sure what you push on once it's in there but my guess is your just levering up the shackle.

good luck

it does have a post in the center of the keyhole (shaped like the number nine "9"),and after messing around with it a bit,it appears there is a locking bar of some sort.
i think that will need to be under tension,and i think i would have to make something out of an old key
( i am SO newb when it comes to levers...)

I just something that may be helpfull to you. If it's the more modern of the lever locks in the time period that it was built, it would have a locking plate. The plate is pushed by the toe of the key, once all the levers are at the right setting, to tension it, the plate would either be at the back face of the inner cavity, or the front face of the inner cavity. So you must be pushing the bar to the clockwise while picking the levers, otherwise you can't set the levers. I'm trying to post a drawing of what I'm describing but I don't understand how. To use the img thing on the reply bar, does it have to be on the internet, or is there a way to take it from your desktop?

did you figure it out yet?

slow progress,but ,yes,i am just lacking in the proper tool to tension the locking bar.
thanks for your help.

a thin gauge (1.6mm) section of piano wire should be enough to tension the bolt stump, you can work out the height as it will be almost the same height as the keyway, and with only three levers a second wire to lift the levers should work, take a look at John Falles lever picks
