Lock ID and Combo change information needed

[hammerslammer]

I need some help identifying this lock and the required change key. The safe is still in service so I'm trying not to screw anything up too bad.

It looks similar to a later version of the Mosler Port-A-Vault, though it is differently built. I wonder if it is made by Mosler, because the handle of the bolt retractor arm is different than mine. It looks like it has the great arms of the great seal on the front, so it was likely made for the US Treasury Department. Can we get pictures of the great seal at the top of the door and the item just above the date at the bottom of the door? Does yours still have the paper on the inside of the door with the combination change instructions?

Obviously, the coins on the dials indicate the locks are manufactured by Sargent and Greenleaf. They are four wheel locks, so each has 100,000,000 possible combinations. The balancer bar between the locks of your safe is currently set to require only one of the two locks to have the combination entered to open the safely. It is changeable so both combinations are required in order to open the safe, as was originally set when the safe was new. Do you know both combinations? Don't post them here, just want to know if you know them both.

In fairness for the questions asked above, here is a post of my Mosler that your safe looks to be based on.

Have a great day,

Gordon

The safe is still in service at a USPS office and is used to store stamps and other accountable items. Only the top lock is used because there is only one person responsible for the contents. The problem is apparently that person might have some sticky fingers(allegedly). Now they need that combo changed and the accused is not being forthcoming with the old combo. I'm assuming that I can remove the back cover and align the change key holes to get started. I think I also have to remove the bolt during the change? We covered this type of lock during training, but only briefly. I went ahead and locked it open so no one could close it. I don't have the change key currently, but I think a SLC-21 will work? The paper is still affixed to the door, but it has seen better days.

We have several of these safes still in service, and some of them are truly works of art. I'll try to take more pics with the back cover off when I go back. Might as well do a PM on the linkage while I'm there.

Thanks for the response.

I'll check on the change key as soon as I can. I'm currently on vacation a few thousand miles from home and my reference material, but I'm visiting one friend today who may know, and can/will call another couple friends who would know. Time zones are at play in contacting the other two people. But we will get you an answer!

I think there is no locking on by combination on this lock, so since the door is open I would first take off the backplate of the locks and just watch the gates line up to learn the combination.
To change it: if you can’t find the correct change key, it is possible to make one with a large nail on a grinder and set the wheels to change mode with the backplate off, but please don’t do that unless you really understand what you’re doing.

Hope some of this helps

And as always: Do check the combination at least three times before closing the door!
