I'm curious if anyone knows where I could find what the original efficiency would have been for a new Burnham boiler model 805B

    I don't know how specific you need it but it was in the very low 80s.

    It's rated efficiency might have been in the low 80% range but actual operating efficiency was in the mid 60% range at best.

    My wholesale house sold Burnham so I am pretty familiar with their operation.

    right, AFUE is not a good representation of actual efficiency
