Antique Safes/HHM safe lost combination


I have an old HHM safe with a S&G combination lock.

Safe was purchased 18 years ago in West Helena, AR.

Is there a list of possible default combinations?

If not how likely is a locksmith able to manipulate the lock.

I am now in SW Kansas and it has not been opened since purchased by my sister-in-law, I am dying to know what is inside.

It looks very much like the one in this answer:

Hand written on the side of one hinge is R2607 does that mean anything to you?


Hi Matt,

There is no such thin as a "list" of default or factory combinations.   A "default" combination would be one that always opened a safe or would reset back in case a combination is lost.    Locks don't work that way, and safe makers didn't use a "standard" combination.
First off, with over 1,000,000 potential combinations available, there is little reason for them to use a standard, combination.   You could sell a heck of a lot of safes before ever having to use a combination over again.
Second, manufacturers NEVER published any listing of serial numbers or the combinations set on safes, for obvious security and liability reasons.   Once they are out of business, any records are lost as well.

So, with a locked up older safe, with an unknown combination, you basically have two options.    You can test all of the possible combinations that your lock might have, or you can have a safe technician open it.

NOTE:   As you asked about "locksmiths",   I generally DO NOT recommend using them for safe work as they usually don't have the training, knowledge or tools to work on safes, without causing excessive damage or charging exhorbant fees.

As for having the safe "manipulated" open, while it is a possibility even many safe technicians are not skilled manipulators.    Unlike the movies where they simply wave their hands over the lock and say "These are not the Droids you are looking for" (oh sorry, wrong movie), manipulation is a very exacting skill requiring LOTS of practice that most service techs are not willing to put in.

While I would discuss the possibility with whom ever your local safe company and safe tech are, they may not be trained.

Drilling the safe, while not preferable, if done correctly by a trained safe tech, will NOT damage the safe or lock, and the usually small hole (around 1/4") can easily be repaired.

The numbers on the hinge are casting or part numbers, and have no other meaning.    Manufacturers NEVER published any records pertaining to safes or safe combinations, so even if we had a serial number for your safe, there is no place to look for the combination.    As HHM has been out of business since about 1959, there is also no one to contact.

Check your yellow pages under "Safes & Vaults" to see what companies are in your area.   If you can't find one, let me know where you are located (zip code) and I'll see if I know and/or can recommend someone in your area.
