The Pratt & Whitney #10 Production Milling Machine

This small Pratt & Whitney is the gift of Mrs. Arthur Redpath.  It is a "hand" mill - instead of a leadscrew and handwheels or power feed, the table is moved left-right by the wood-handled lever.  Such machines were typically used for production work.  The chain drive, although appearing to be a later adaptation, is in fact original.
