Not really intended for general work but a specialised machine for reseating valves the Leavitt was manufactured by the Leavitt Machine Company and marked: Dexter Valve Reseating Machine, Orange, Massachusetts. With a V-way at the front and a flat way at the back, bed was 22.25" long and carried a headstock  fitted with, rather surprisingly, a 3-inch 3-jaw chuck branded "Leavitt". If the chuck really was manufactured by the Company it points to a serious commitment to volume production for these are not the easiest of things to tool up for and manufacture.
Of utmost simplicity, the  tailstock was equipped with a plain bar that end in a supporting centre. Also unexpected,  instead of a single swivelling tool slide the Leavitt was fitted with a proper compound slide rest - though on the example shown below the top-slide handwheel is from a Sherline.
