Yes, 87" swing, I do not know the original swing over the ways, but it was rated at 40". I'm sure that the actual swing over the ways was in excess of that, the headstock and tailstock were raised by welded steel housings and the compound was raised by a hydraulic tracer slide, which was made in house and used a Monarch air bleed stylus system and power unit. I assume that the headstock may have been a bit shaky, as it was braced up against the wall behind it. I looked up the manual, it was advertised with an actual swing over the ways of 44 1/2" and was built in 1941.
Another thing that was done was to fabricate a faceplate to go over the original faceplate that mounted 4 faceplate chuck jaws in slots that located them radially and also prevented radial movement with cross slots and keys, each jaw being held on by four big bolts. I can remember running it only once, but was the favorite of the journeyman who often ran it when it came to change the chuck jaw locations, it took two people to do the job, one to pry the jaws out of their slots (my job) and the other to pull the jaw off and relocate it, the me again to start the bolts and draw the jaw up to the faceplate, I'd guess that each jaw was on the order of 50 lbs weight. They also had a shop built pit lathe with a approx 12'ft swing, it had, I think 12 chuck jaws, a real chore to change, being assigned to work on it was like being banished to Siberia, it seemed to only run in winter, in a shop with open doors and cold winds blowing and lots of loud noises, as it was the fabrication shop with hammering, arcair, air grinders, you name it, about every discomfort one can imagine.
