Help Learning About 3 Dial Alphabet Combination Lock

Hi,

I have this lock, but don't know much about it. I would like to know what it was originally used for, where it came from, how it can be used again, and what the value of it might be.

It has 3 alphabet dials, and one key. The key looks like a knob. The lock sits in a case and looks like it can be mounted. In between the device and its case was a metal plate. The plate says manufactured by SABENA. My understanding is that SABENA was Belgium airline that closed in 2001. It also says Serial N is B747-2. We received this item along with other items of a B747. So I'm curious if this lock was used by the airline or in an airplane. The date listed is Oct. 84. The P/N is 1-10569, though I have not been able to find anything about that. I do not know what the information on the right side of the plate communicates.

If anyone has any insight as to what this lock was used for, I would love to know. The closest thing I could find to it was found on a website about Antique Swiss Bank Safe Deposit Box Combination Lock.

Would this lock be able to be used for something again? What would it work best for?

Though I'm so curious about the functionality and being able to include it in our lives somewhere, I'm also curious of its value. The lock intrigues me, but if it has worth I'd be willing to part with it as well.

Thank you for any information you give, or any helpful direction you can point me in.

Can't confirm its use by airline companies but it is the sort of lock they might well have used and is typical continental European design. As far as I know this similar version is still being made by KabaMauer- think it's the KMM81033 combi

It's some sort of locker lock, as said above. Safe deposit locks like this also include a lever pack for a guard key, so this is not for a safe deposit. Any sort of secure locker might use it on a plane, or elsewhere. Aircraft sometimes carry high-value low-volume cargo such as gemstones or postal packets which do not go into the hold — passenger airliners do not all have holds.
Locks such as this can provide dual control if needed. The combination, unlike the key, can be easily changed.

Strongbox44, forgot to add what little I have found, although unfortunately it doesn't relate to any connection with the airline company.

Seems your lock was made in Holland by the manufacturer LIPS, and the other company just badged it Sabena- does seem quite a rare lock though, very little info out there and LIPS made versions with 4 dials in a square configuration which seem more common.

Also, totally unexpected and unconnected but it just so happens that these were apparently the sort that were attacked in the infamous Antwerp diamond heist back in 2003..
