I have recently come into posession of two toy steam engines and a boiler my grandfather built about 95 years ago. My concern is with the structural integrity of the boiler. Can you advise me how to determine if this boiler is safe to use. The boiler has no gauges on it to determine pressure, so I will need advice on proper gauge specs.

I don't know the answers to your questions, but I do have a safety tip:

If you pressurize it to test it, make sure you fill it completely with water first. Air is compressible, and it will store energy as the pressure builds up, releasing that energy all at once if the structure fails. Water is incompressible, so it will not release stored energy if the thing bursts.
