Believed to be a Dalton Six (though of a version not recognised even by aficionados of the make) the early unrestored Dalton shown below was manufactured circa 1920 and reveals some similarities with the Combination Machine. The lathe is typically Dalton (with the maker's name cast rather faintly into the face of the apron) with an unusually wide bed, the ways continuing past front and back of the headstock and with very long and supportive saddle wings. The headstock on this example is a heavy-duty pattern with a twin-bolt front bearing and what looks to be, for its era, a reasonably large spindle bore. At the top of each bearing cap can be seen a traditional Dalton oiling  pipe, normally covered with a fluted cap secured against loss by a wire keeper connected to the pipe's lip. Although the compound slide rest lacks micrometer dials a fine rate of power longitudinal feed is fitted, just like a "lot 5" model with a worm gear driven by a key running in the slotted leadscrew. As Hubert Dalton came from England in around 1904 it's unsurprising that the toolpost is a typically English design, with the triangular clamp plate held on a light spring and levelled with an adjustable screw - such an assembly being rare indeed on any American-made lathe. Missing on this lathe, but present on all other Daltons, is a T-slot running down the back face of the bed. Another Dalton Six (unmistakably so labelled), can be seen here
