Recently I picked up an old coal forge in good shape to add to my Blacksmith shop.
This size of cast iron forge would have been common in shops between 1900 and the 1950's. Buffalo forge was one of the largest manufacturers of forged, and is still a major maker of air handling equipment.
This forge has a very smooth working hand-cranked blower. It works well, turns smoothly, and is fairly quiet. Often an old blower is loud, temperamental, and loud! I got lucky.
