Re: Old Combination Lock

Got a dial for this lock. Very good quality with a 6-lever lock built in. The spindle is rather long (something like 30cm). I do not see how to remove it. I do not want to cut a historic spindle. I would like to mount everything. So what do I do?

Someone else made a simulated thick wall safe by taking two steel plates and fixing them apart from each other. I can’t remember who but it was a Diebold 177. That would probably work well here since you want to leave the spindle intact.

Re: Old Combination Lock

I made a mount for this lock with three wooden boards - one for the dial, one for the lock and one for the spacing.

Today I also manipulated it. I never had a lock showing all gate so well. Each gate is 3/4 numbers deep and 3 to 5 numbers wide showing in the order 3/2/1. That is what I had expected, because the fence looks to me really tilted.

Re: Old Combination Lock

Nice! Always feels good to get an oldie going again, eh?

If ya ever feel up to it, would be nice to see pics of your mount.

Re: Old Combination Lock

Martin - someone on eBay was selling this lock and practice stand a few weeks ago.

Two clear plastic plates, with four long bolts between them. Infinitely adjustable for spindle length. Like all beautiful designs, I don't know why I never thought of it myself, it's so obvious when you see the picture.

Re: Old Combination Lock

Here it is. Not as versatile as the plexiglas mount, but nicer for display. The two lines in the non-numbered area of the dial mark the contact points. The wood is beech from waste of a kitchen setup.

What type of lever lock does it have, as in what key it is? Never seen a lever lock in a dial.

Re: Old Combination Lock

It is a 6-lever chubb-type lock. The key is symmetric and can be inserted either way. Dial locks at 50. There is another lock type for dials, which is like a mini pork pie: http://blog.tresoroeffnung.de/2010/09/2 ... protector/ (Don't know if this was in a dial, but I know a dial with that type of lock.)

Re: Old Combination Lock

I'm now sure the lock in the link is from a dial too. The full dial I know is from Franz Garny dial with a newer 15B (serial in the 50000s). Mine is a Franz Leicher dial.

Re: Old Combination Lock

Manipulation graph. The fence is 0.3mm thicker near the lever than near the tip. I guess the guy filing the fence was not as careful as he should have been.

Re: Old Combination Lock

The 2 marks on the dial between 100-1, they are your contact points? Neat looking lock and mount. What do the letters on the back on the lock stand for? German for LOBC?(Locked On By Combination).

55-18-73 is that what I see in your graph?

Re: Old Combination Lock

Yes, the two marks are the location of the CPs. The numbers on the graph are from a sheet I stuck to the dial for manipulation.

DRGM = Deutsches Reich Gebrauchsmuster. I assume you know Deutsches Reich. Gebrauchsmuster is a type of patent. I think it is cheaper, easier to get and not as long lasting. Maybe that was for the changable key hole pipe.

I used 56-19-74 to open the lock. W3@L55 did not open.

Re: Old Combination Lock

Disassembled the setup for you. Key bitting diameter is 14mm. One of the springs seems to be missing, but I am not sure because there is nearly nothing in the lever which obstructs the movement of the bolt stump.

Re: Old Combination Lock

What a neat old lock. And I know it can be a pain sometimes,
but I do appreciate the photos! The mount btw, looks great.

It's just nice to see the dial up close, and even the graph.
Really helps put your whole experience into context.

Another one for the shelf :)
