I have a thirty plus year old Craftsman router that was given to me by a very nice old gentle man who said it was too powerful for him . I have taken it apart and cleaned it . I have used it for about five hours I would guess it is near new condition . I am looking for an owners manual for it .I was told by a Sears representive that it was originally manufactured by Ryobi. The model number is 315-17380. If anyone could help me it would greatly be appreciated thanks again Mike Black
