From a low resolution photograph like that it is pretty well impossible to identify it.
It is a 100+ year old fireproof safe. In those days there were dozens, possibly hundreds, of makers producing these throughout the black country and beyond. The round brass knob is a give away that it is very old.
The principal reason for such a safe was protection from fire. This was achieved by putting a filling of hardwood sawdust and alum crystals between the 2 skins of the safe. This worked but in a unit as old as this it will have packed down over time and will be virtually valueless. Security against theft is negligible. It will stop somebody just walking off with the petty cash box but do little more. Some insurance companies will give a minimal overnight cash coverage for cash kept in a locked safe. You might qualify for that but little else.
As for restoration- what is there to restore? The lock is likely to be clogged with dirt. So strip it and blow that out. Some lever springs might well have broken in which case they should be replaced. That is a job anybody can do. Jut take the broken ones out and squeeze new ones in. Then cut to length. There are probably 5 levers. If you do clean it out make sure you put them back in the correct order or it won’t work. If there is a chance that somebody else has got a key then swop them round and get a locksmith to cut a new key.
As for value- it is negligible. There were thousands made and as a no name generic fire safe you would be lucky to get somebody to take it away without charging you.
Sorry to sound so negative but that is the truth. If you really want to keep it, by all means PM me and I will talk you through what I would do to make it a bit more secure but beyond a clean and a fresh coat of paint you are on a hiding to nothing!
