Herman Nelson, Trane unit heater sizing

I am trying to locate BTU capacity, EDR, and/ or pounds condensate per hour on the

following steam fan forced unit heaters: Herman Nelson model TSU 1031 and a

round Trane model 100P.  Both are at least 40-50 years old.  The boiler pressure is about 5 psi. The Trane unit is round and the herman nelson  is rectangular. Thank you in advance!
