Locksmithing/Mosler Safe Question


I saw you have made other posts about Mosler Safes. I acquired one from an oil terminal I am working at (given to me due to the fact its an old safe they used to use for a cashiers office when they paid employees at the job site back in the day). I would love to gain more information about it and you seem like you know a lot about them. The door was left for years OPEN but in the locked position. I figured out by pulling the dial guts out the combination (thanks to tv) and it is now working. The info I got off of the tag inside the door is that it is a Class II and it also says Class Fire B with the serial number as 105528. There is also another marking I cant quite make out but I believe it says T-20. Any info you could throw my way would be really appreciated. I was thinking about blasting and painting it and either keeping it or selling it. Any ideas on what this type of safe could bring in?


Obviously I will need to see your safe for any type of evaluation.   The information that you have provided indicates that the safe is a pre 1960 fire resistive safe, with a "T-20" tamper resistance rating.  This is NOT a burglary resistive safe, and should NOT be used for overnight storage of cash, jewelry or valuable documents.
As the safe is over 50 years old, it also does not meet current standards for fire resistance, and it has no resale or commercial use or applications.

While it may still have some value, it isn't as a "safe".

In order to answer specific questions, identify, evaluate or appraise your safe, I'm going to need photos.  They should include full exterior and interior.  Detail photos should include pictures of the dial, handles, hinges, artwork, locks, bolt work, castors, cabinetry and any special details or damage.  Note:  You may have to remove the back panel on the door to gain access to the lock & bolt work – I will need these pics.
If you have a particular detail that you have a question about, I will need a photo of it along with your question.

I will also need to see any documentation that you have in regards to your safe.  If your safe has a unique historical perspective, you should be able to document this with letters, newspaper articles or photos, if not it is simply a story and will have no bearing on the value of your safe.

Please use as high a resolution as possible so that I can examine details of your safe.  Pictures which are low resolution, out of focus, or from a distance don’t help when we try to evaluate the container.  Note:  with higher resolution, you may only be able to send 2-4 pictures per email, depending on the size of the file, I have a 10mb limit per email.  If photos are larger than 2mb each, you may only be able to send 2 or 3 photos per email, requiring several emails.

Please don’t send me “cell phone” photos.   Also, please don’t use on line photo drops as most of these also don’t allow me to easily access the photos for examination.   Send the pics directly to me, while this may be more work for you, it will make my job easier.

Please send all of the requested photos to:  andy@securitysafeusa.com

Note:  As I am in the field several days each week, covering a huge service area, I may not get back to your photos immediately, but I will respond as soon as I get an opportunity.  Due to field work, emails may tend to get backed up which means I may not answer them immediately.

Our informal evaluation is at no charge, however if you feel you need a formal evaluation or appraisal for insurance, estate sales, donations for tax write offs, or to establish it as an antique, there is an administrative fee for this service.
