 Mosler T-20 Safe Worth Using as Gun Safe?

Found a guy trying to sell what he describes as:

This is a very LARGE, Mosler, 4 Hour Fire, Double Door, Safe on wheels. It would work Great as a Gun / Rifle Safe. Tagged as a Mosler Class Four Hour Fire, Burglary Class T-20. Comes with 3 adjustable, removable shelves. You don't see safes of this size and quality for sale very often so don't miss out. Safes of similar size and only 2 1/2 hour of fire protection sell for $7,000 elsewhere. This Mosler Safe is in GREAT working order and is still being used today. The 3 number combination will be provided to the buyer once payment is made. The Gary Free Standing safe, shown in one of the pictures, is not included. It was sold separately. The Locking drawers on the right side can come with safe at buyer's choice. Safe's OD: 52" W x 34" D x 75" T Safe's ID: 41.5" W x 20" D x 60.5" T

I'm somewhat local. He's asking $3000 for it.

Anyone have an idea on the age of something like this, how good the lock would be, and whether it's more of a fire safe or a burglary safe? Also what do you think of the price.

Debating a new safe, or whether to build a vault, etc etc, but something like this in the garage might also do the trick for the next 10 years or so.

These big data safes had their 15 minutes of fame back when large volumes of diskettes and tape reels needed to be stored. Although they are still made, it is rare to see the large versions since so much data can now be stored on very small devices. Without seeing a photo, I would guess at least 20 years old.

It is a fire safe, that will offer limited burglary protection. A T rating is a tamper rating, not a tool rating. It's very similar to an RSC rating seen on modern gun safes, but for 20 minutes instead of 5.

Used fire safes have very limited commercial value, so I would say his price is about twice what it should be.

I have a couple of the Mosler Data Safes. Here is a pic of one I pick up at an auction years ago. Without the 5" wheeled base it sits on it would be
approximately 75" high. It is about 52" wide and 32" deep (external measurements). If I remember correctly, it is about 62" high inside and about 18" deep. I think they are great safes for storing ammo.

I just bought another one, a little smaller 70 inches high without the 5" base, for about half of the $3k you mentioned so I would agree with A1's assesment.

Don't forget, its more than likely insulated with concrete.
4000lbs on 4 little wheels will not go anywhere except concrete.

And the price sounds a little too high.

Good to know about the price being way high. As compared to say a fort knox or liberty, what are your thoughts for burglary protection? I am looking at all my options right now as my current fort knox 7241 is full... If it is slightly better at burglary than a RSC, at least that might be better than another ft knox....
