A.O. Smith Boiler Age

I did an inspection today and the boiler was an A.O. Smith Permaglas. Model # HW80.
Serial # 600 61 7 A 0405. The house was built in 1971. This may be the original boiler but I’m trying to get a build date for the buyer. I don’t see anything on Building Intelligence Center listed for AO smith boilers, only water heaters. Does anyone know where else to look for information? Thanks.

The color alone tells me it’s likely original to build.

I agree…for 10 characters needed.

What do you mean " 10 characters needed?

The forum requires a 10 character minimum response.

LoL. I thought that you were talking about number of digits for the serial number.
