The lock is either a Mosler 10 1/2 or a Mosler 5. The 10 1/2 has 3 wheels and the fence is pushed into gates by a turn of the handle. A turn of the handle (probably clockwise) will change a lot how the dial can be turned in this lock. Maniulation would probably be like with other direct entry locks. Dialing direction is mostly unimportant. Important is, that the final turn is to the gate of the drive cam, which should be at 34. The Mosler 5 has 4 wheels and a friction fence. Turning the dial should create the sounds of interacting gears on this. Manipulation is like a normal friction fence lock, i.e. with only one which is while turning the dial counterlockwise. This is also the final turn to stop to open it.
The paint looks to me just like some has fallen of. All the lines and letters look original. I am sure you can reconstruct the most of what is missing. The finials are difficult to find as an original part, so some people have started ot make new finials.
