What Does This Hold?

Interesting; mine is Morse taper #2, has none of the imprint, but is definitely the same type of holder.
Thanks 4gsr!

It's been many years since I've messed with Superior stuff. The 1/4" cross pin is where the honing mandrel latches in place. The stone has a flat wire with a bent end that lines up with face notch. when the nut is rotated, it traps the ear on the flat wire. During operation, you're supposed to be able to grab the outer barrel of the hone head and it has a built in threaded piece that should suck in the honing mandrel so it can get a new "bite" as the stone wears down and the hole opens up.
The "Tool Room Kit" was probably the companion to this piece as kd4gij mentioned. Since there was two others mentioned on eBay, it more than likely shop made by Superior.

What would be honed with these? Just any kind of bore or something more special? The list of thing about which I've lived 60 years in ignorance keeps growing.

I've used them for straightening up badly bored holes or get the surface finish up to where it looks pretty and nice. Use them to improve the surface finish for any sealing bores.
It's tooling that is almost obsolete in industry today. Honing today is primary used for hydraulic cylinders and long seal bore devices such as packer mandrels and seal bore extensions as I'm used to working with down hole completion tools used in the oilfield.
 
Where I used to work up until 3 years ago. we had a sunnen horizontal hone the used about the same setup. We used it when a bore had to be within a phew tenths such as ring gauges. Also used it when a bronze bushing was a little tight after pressing it in.
 
With the correct hone & mandrel, could I put it in my tailstock and use it to clean up my headstock's MT5 bore?

Theoretically yes, but that is really not the way to hone. Ideal is to rotate the hone while moving it axially to achieve about a 45 degree crosshatch. If you could move the tailstock in and out at the correct rate then it would work. If the hone was just left in one position, the surface would be completely trashed due to inconsistencies over the length the hone stones.

If I were going to hone a MT5 taper, I would get a small engine, 3 stone hone and use a battery drill to power it. The other key to honing success is to flood the work with honing oil to carry off the grit and swarf to keep the stones from plugging with crud.
