Here is a pic of an ASW 5" stove damper, This was a damper on a wood stove we had in our first tiny home back in the 1970's, When we sold the new owners did not want the stove or the chimney so we removed all of it, The stove is long gone but we used the damper on a wind chime we made.
We purchased the damper from an old family owned hardware store that had been a family business for over 100 years, Who knows how long the store had the damper in stock before we purchased it.
