This motor is an estate find.It appears to have never been used.The plug for a cord attachment is still sealed and there are no markings on the bottom from mounting.In addition there is no dirt or dust in the motor area when looking through the vent,another indication that it has never been used.Although I am not knowledgeable on this particular item,this is my assumption.It does have some scratches and paint peeling from storage.If any additional information is needed for this item please email me.Thanks for looking.Selling as is
