Via some deep internet digging I have discovered that this lathe is a 1933 9 in swing, 4 ft bed South Bend New Model Simplex.
Now I need to find a half a bucket of change gears so that I can cut threads. They are 16 DP with 5/8" centers.
BTW, the original paint color of this lathe is the same color are an AD 216. I call that color 'oily grime dark gray'.
