Holly age, please

[Russel Ray]

I found a brand that I've never seen before.
It was a Holly.
Model number 80 VF
Serial number 1220

Judging from the condition, it would not surprise me if it was made in December 1920, or the 20th week of 1912, especially since I was at a 1912 house.

Nonetheless, anyone have any information on the age for this unit?

Thanks.

Hi Russel,

Prestons list that as being made in 1965.

BTW, it has the lowest AFUE I have ever seen at 54%

Regards

Thanks, Gerry. That would seem to coincide with 1958-1968 expansion and remodeling of the house I was at. I don't think it's been serviced since it was installed, though.
