Gas fired Boiler age?

I am trying to date a National US Radiator Corp. boiler. I am guessing 40-50 years old

It shows a Boiler Number of 6-11B, but no serial number. Can anyone help?

    can you post a pic?

    If you look under the beacon boiler reference here in the library, there are 2 different sections of national boilers prior to 1959 and after 1959, but I couldn't find your exact boiler number. maybe a pic of the tag your looking at would help.

    My guess

    I'm guessing it's about time to replace.
