To determine if the safe is insulated is easy...just remove one of the inner door panels and look for a vermiculite mixture in the's similar to concrete.

A couple of tips for you...the insulation in your 1920's Mosler safe has probably dried out long ago leaving the safe less fire resistant. Although I've seen antique safes do surprisingly well in a fire you can never guarantee the content's survivability due to a fire can burn for different lengths of time and different temperatures among other things...

Newer safes are tested by Underwriters Laboratories for fire resistance which protects the interior from exceeding the testing temperature limits for a period of time.

Nothing is fire proof no matter what a salesman will tell you...

Also, I wouldn't keep antique guns in any unheated warehouse, the cold will transfer into the safe and affect the guns sooner or later...

Invest in a well made insulated gun safe for your antique gun collection and coins if you can afford one. Don't buy one of the sheetrock lined steel boxes you see at the big box stores that they call a "safe"...most probably wouldn't protect in a real fire...
