Garrison was a very popular stove line in the time period from 1978 to 1982. The full line consisted of 3 sizes of wood stove and 1 coal unit. The first model was the Garrison I, a large steel stove with an 8" flue. This was followed by the Garrison two and three, smaller units with a 6" flue. All had rear takeoffs which allowed for easy venting into an existing masonry fireplace.
