How old is my Richardson?

Cutler Member Posts: 2
I bought a house that has a Richardson coal furnace converted to oil with diverta-tee hot water. Hard to read the plate on the boiler but I think it reads A71(7?). I'd like to know more about this unit.

    Found a serice tag

    from 1987!
    States burner is a Crown Deluxe App No 1452d
    Nozzle size 1.00
    Angle 80
    Spray H
    Efficiency 75%

    How does one measure the efficiency of an old boiler?
