Hand Fed Coal Boiler: National Heat Extractor , 200 series, boiler # M-205

Greetings,
Bought my home about 35 years ago from an elderly gentlman, Emil. A very smart guy-graduated as engineer from Carnegie Tech (now Carnegie Mellon -class of 21!). I have a gas fired steam boiler- gravity system/one pipe tied into the former coal/wood fired boiler tied in to piping system. To switch just close return valve to gas appliance, open to coal fired and open outlet for coal fired steam to enter piping to radiators throughout the house. I once fired it up w leftover coal in middle of January and had the place super warm-probable too much.
So, thinking about firing this baby up again since I retired and can maintain the fire, monitor operation. A couple things concern me: condition of chimney, I believe it's unlined, and condition of boiler- a bit of rust at the site glass w small leakage of water there. Boiler has a pop off valve and another "valve" to control air flow at bottom rear of boiler that appears to be heat or pressure activated as it's adjustable weight slides back and forth as an adjustment of some type .
Sorry for long post-war think it would be great to fire it up,save some cash, Frank the heat. All comments and feedback appreciated. Basic pics attached

The guys are going to ask a hundred questions. Give as many details up front as possible. Oh, and pics of inside the boiler are always interesting.

The first thing I would do is attach a compressor to it and put a few pounds of pressure in it, see how well it maintains the pressure. Not familiar with steam but the internet is telling me the relief valve is usually set at 15psi so I would keep it at 10psi or less. If you have any major issues now is the time to find out.

I had customer with boiler like that, looks to be the same type/model. She burned mostly pea in it, about 10 ton. She would also have about 2 ton of nut presumably for the coldest days. It was older Victorian type house that was pretty big.
