AJAX AJT-2 and AJT-3 (AJ-2 and AJ-3) Turret Milling Machines - These were built in early and late versions. The earlier model had a vertical head with two parallel rows of push-button switches on the front face with the 2-speed motor switch immediately above and, on the top face of the head, at the front, two levers - one of a toggle type the other moving radially in a slot. The head on the later lacked the electrical push-button controls. This is a combined manual for both early and late models.
