This company made the "M & M" planer/molder, a predecessor to the current Williams & Hussey planer-molder. There were two models, with 6" and 7" capacity, respectively. Parts are no longer available for the 6" model, but Williams & Hussey parts are interchangeable with the 7" M & M model (W-7).
Parts and Service
There is some interchangability between knives of the M&M and Williams & Hussey molders; see this posting in the OWWM forum provides some information.
