How old is this bugger??

It’s a Republic Furnace Model# F100 Serial# A2450. I cant find a thing. House was built in 1941. Thanks in advance. A.J.

According to the CD Tech Ref Guide Republic was bought out by Autogas, and they (Autogas) went out of business in 1972. They didn’t have any aging data.

With those numbers, 41’ would be a good guess.
