SIGP2101, thanks for the tip about hovering. I guess my Ipad didn't do that. It didn't hit me until just now what that photo in the last of the Colt series was. That "bank vault looking contraption "behind" the machine? Is that an indexing tool head? So turning it connects a new tool to the drive? Incredible. 100 years before CNC...

That is exactly what it is/was. On the back of the picture:
"The use of the revolver frame jigging machine is demonstrated by a Colt worker. This machine could cut both the interior and exterior surfaces of a revolver frame. The inner hub of the machine is engraved "Col. Saml. Colt Hartford Ct." The employee wears a unique hat that is square at the top and seems to be made of folded paper.

In essence it is a mill with multiple heads that holds various milling cutters. Fascinating, is it? Here is a bigger pic. Click on it.
