This machine certainly looks to be basically the same unit in your post #7 John. Read the write-up by LeBlond for these machines in the previous .jpg. According to LeBlond, they would use a motor that could be varied from 500 -1500 RPM. There were 4 mechanical speed changes, with the other spindle speeds controlled via motor RPM. The write-up states that at least 80 different spindle speeds were available in geometric progression. Given that the there are 4 mechanical changes, that means at least 20 electrical speeds. Whoa!
Article goes on to state that these lathes were designed for extra heavy duty use, namely in steel mills, and railroad shops. With a 30" swing (which the article says was one of the sizes available), and 8' between centers, the weight must be way up there. 8-10K lbs. perhaps?
Looking at the photos closely, it doesn't appear much is broken. Obviously the motor arrangement has been altered, but from the top of the headstock down, it looks pretty good. The only lever I see broken off, is the tumbler lever. Would be nice to see some views of the tailstock.
It would be great to see this transitional machine preserved. I know I have never seen anything like it.
Edit: 27" swing per John's post #7.
