This restoration is on a model "M" round knife cloth cutter made by The Wolf Machine Company of Cincinnati, Ohio, USA. The company had been in business since 1888 and still makes these types of products today. My best estimate places this machine being made in the early 1950s. This tool made for a very interesting restoration as I came across several parts and problems I've never seen before. Most interestingly, this machine runs on a 25 Hz electrical network which only existed in small ares around the Great Lakes region in North America from 1895 to around the 1950s. Other than the motor, the entire machine has a much smaller amount of steel components than you would imagine. In the end I will probably use this to cut all my pizza from now on.
