Dayton Model 5K339N 1/3 HP 1725 RPM Electric Motor. I got this in a lot at an estate sale for an electric motor service shop. This motor is in great condition showing minimal use. I have no idea what it was originally used for. Motor is clean and worked flawlessly when tested. ITEM SOLD AS SHOWN AS FOUND PLEASE ASK QUESTIONS AND ASK FOR MORE PHOTOS IF NEEDED THANK YOU.
