Alcosa forge blower unit powered by a Brook Gryphon 1/4 HP motor, very long term stored as a spare until I rescued it years ago.
Would have been for either a school brazing hearth or small blacksmiths forge, I was going to use the motor off it, but seems a shame to break it up.
Runs fine and the compressor bit was stored full of oil, hence big stain on workshop wall!
Plate states 3.8 CFM at 2.5 psi might do for a small furnace, very heavy so would not post, though if desperate I will pack and weigh for your courier.
First part of downsizing clearout, why did I collect so much stuff?
