      SOME lathes had collet seats in the tailstock......

      For such a machine, that could be a kind of "box tool", with a place for the stock to come in through a bushing, , a place for an adjustable cutter, and presumably a hole for the turned portion to enter.......

        Watch this Utube video on thread grinding and about half way through you will see this device in action at about 2:41 min into the video. looks like it is used as a driver on the spindle end of the setup.

        and it's a pretty cool video too

          That is actually a totally different item........... A dog driver of the gear-making type.....

          It lacks the front end part of Snowman's device, which would have little or no discernible function in the CNC video type application.

          However, it is true that there is the traditional three-screw adjustment in Snowman's device, similar to a dog-driver. But I suspect that is actually intended to adjust the position of the cutting edge so that it is in correct position relative to a radius line.

            OK, I'm reverse guessineering.

            Those setscrews in the middle look like they'd hold HSS tool (ground to the application)

            the shank is keyed, threaded and has a taper which would align it in the machine. The shank also looks battered, gouged, etc. Suggest to me it does not fit in any kind of precision, rotating machine tool. So, a production jig, used by unskilled labour.

            The setscrew at the "front", holds a bush. So designed to accomodate a variety of bar sizes.

            So, a wild guess is some kind of production jig, for unskilled labour to turn a profile on the end of bar product.

              the shank has a little rust, but it's very similar to a south bend collet i believe, i know it looks similar to the 5v collets i use in my van norman, just smaller...also similar to those in my smart and brown lathe, again a little smaller

                Its a Box Tool, meant for a non rotating spindle. ( Turret lathe )
                The square tool holder has square head screws, very common on box tools, as they make for quick and strong clamping.
                The collet is hollow and allows a shaft to go through it.
                The solid plug, also with square screw is a stop.
                This tool would have a bushing for work diameter feed to go into the toolbit.
                Since it is solid, it probably was used as a "Stop" when feeding the bar in
                at the start of the cycle.
                Normally, a bushing would be used here to match bar diameter
