Age of Coleman Furnace

What is the age of this Coleman Furnace?
Model #2632D Series, Serial # 8686263,

Thanks!!! in advance.

Hi Buck,

that sounds like an old mobile home furnace, Prestons list it as current between 1966 and 1975, thats a close as I can get it



This is in a 38 year old house. It is mostly likley the original…
