Not sure how old this baby is, but I'm guessing late teens or early 20's. My wife's grandfather opened a butcher shop in 1920, and we're going through it last summer and find this thing sitting under layers of stuff. Since it still worked, I decided to restore it. Everything is original, including the belt, except for the power cord (now grounded), the switch and two bearings on the blade shaft mechanism. The only real problem is the blade. It has a 1.5" crack from the edge in toward the center. I've turned the machine on with the blade off, and it works perfectly. I won't turn it on with the blade attached, because I'm fairly sure the sharpener would cause a major shrapnel event. I have not been able to find another blade anywhere.
Anyway, I've attached some before and after pics. Comments and/or criticisms will be appreciated.
