Look what I found at Habitat for Humanity of all places. I was there looking for an antique bedroom dresser and spotted these in the hand tools section.

The chuck is a scrolling 4 jaw with 3 sets of jaws. One of the standard jaws is out of sync - probably fell out opening it too much and then not installed on the right scroll ramp. No biggie. I don't know why one of the Jaws has an index pin in it that registers in the slot on the regular jaws. I'm sure it has a purpose though. The chuck was probably made for a taig or something similar but it will get converted into a chuck in a chuck to hold small parts in my big lathe.

The other kit is a set of expanding collets to hold parts from the inside or in a drilled hole. These are beautiful and the operation is silky smooth. I make a lot of custom expanding collets so these should come in very handy. I'll have to see if I can find specs for them.

Also in the box with the chuck was the screw in the foreground. I've no idea what it was for, but the threads are buttress threads, and the head has 4 shallow flats. It's a very unusual fastener.

Crazy to find stuff like this hiding in a restore.

Shoulda seen my wife's eyes rolling when I grabbed those tools. In her eyes, it was just more garbage that her hoarder hubby was dragging home. In my eyes it was like finding a treasure in the sand at the beach.

Didn't find a dresser.

Should I be seeing pictures?
 
No worries, Sus, I’ve got you covered:

The inside collets are for woodworking for sure. Available at Lee Valley. But I'm not above using them on metal.

I’ve purchased a couple of items from Lee Valley (and price-shopped for others): they carry a fair number of things that are “dual purpose.”

Oh, and @jorogi is correct!
 
It is a scroll chuck for a wood lathe.I can’t tell what brand it is. It likely has a thread in the back for mounting. Commonly a 1”x8tpi. It may use an adapter so that it can be adapted to different sized lathe spindles. Depending on the brand, these can cost upwards of $200-300. I have a couple of these.
It has two sets of jaws. The tall ones are pin jaws for holding smaller work, while the short ones are used for holding wood on either on a tenon or in a shallow recess.
The indexing pin, is actually a safety stop pin, so you can’t accidentally scroll the jaws off.
The screw piece is for screw mounting a large chunk of wood on the lathe. If you mount the short jaws, the “head” portion goes in past the jaws, so that when the jaws close, the inner edge grips in the recess. Here’s a crappy screen grab that show how it mounts. NOTE: One jaw is removed for visual aid.

Thanks @darrin1200!

You answered 2 questions that have been bugging me! I'd bet big bucks you are right.

I'm still planning to make a new backplate for it to mount it in a bigger chuck on my metal lathe to facilitate working on small stuff.

Thank you!
