Unless you want to use it yourself,, a restoration would likely cost more than its worth !! The glass would not be easy to find and it looks like the firebrick is broken on the interior !! If that is what I am seeing in the pic !! Then there is the safety issue !! Would it be safe to use in a home ?? My suggestion would be to do a minimal resto and use it outdoors !!

It is flat on top, I believe its primary use is as a wood heater. It is missing the glass on the door

What does the top look like ?? Plain flat or with cooktop ?? It looks similar to the older “earth stoves” !! But then again many mfrs made a similar type !! This one was designed to be either an enclosed heater,some had cook tops,, or open face like a fireplace !!
