Locksmithing/Mosler wall safe


We bought our bungalow home almost 20 years ago. It has a Mosler wall safe built into the brick wall of our basement and the previous owners didn't leave us a combination. :(
I've always wondered what might be inside, since the home was built in 1924!
The cover says:
Mosler Safe Co.
Reg. Patent Pending
Hamilton, Ohio

The combination dial goes from 0-99. It has a dark steel face and is about 12' square across the front, with a hinge on the right.

Hi Jason,

I'm sure you must have read the patent number wrong as the one you've indicated has nothing to do with safes or locks.

As far as finding a "combination" for your safe, you basically have two options at this time:

1.   You can test all of the 1,000,000 possible combinations for the lock, which if you test about 500 each and every day would only take you about 5.5 years.
2.   Contact a local safe company to have their trained, professional safe technician, open your safe.    Note:   I never recommend using locksmiths as they generally don't have the training, knowledge or tools to work on or open safes without causing excessive damage, especially possibly antique safes.

Check your yellow pages under safes & vaults to find a local safe company.   If you don't have one, then let me know where you are located (zip code) and I'll see who I might know in your area.
