age of Old Rheem Gas Furnace

New to blog.

I need to know the age of a Rheem Gas Furnace, Model 3204 80; Serial number L9 W0RCN.
I think it was built in 1950's.

Any help would be appreciated.

My Preston's Guide shows it as 1965 and 1966. They go up in years when they added letters after the 80. Some go into the 70's depending on the letter after the 80.

Thanks for the quick reply. The Rheem Corporate representative told me they had no info in their Data Base on those Model and Serial numbers.
