Looks like the old style coils.
Peel off the fish paper around the outside. Under that 1st layer you'll find the 2 contacts that the wires are soldered to. Peel off the next layer and that's where the coil is. Use small sharp knife to cut away the wire, there's a lot about 1,400'. Fit a 3" long or so bolt thru the hole in the center of the coil. The old ones are 1/4 in dia. Use a nut hold it in place so when you are winding it it doesn't spin free. use a variable speed drill to spin it. Set your spool the wire up on something like a football goalpost so it can spin freely.
If you break the wire while winding just solder back together and put a dab the nail polish on it the insulate it. If you break the wire where it start of the coil you may have to start over. Doesn't have to be super neat or in a particular direction. I've been using 40G wire just because I have some but it's not all that fun to solder the leads to.
After winding check resistance for something around 800 to 1200 ohm. Add a layer of masking tape w/the coil wires exposed. Then solder on the leads to the coil wires. A little bit of hot glue helps to hold them in place. Wrap with a layer or two the tape and that's it.
You might find a better way to do it, this one has worked for me.

When my pals were reading comic books
I was down in the basement in my dad's
workshop. Perusing his Sam's Photofoacts
Vol 1-50 admiring the old set and trying to
figure out what all those squiggly meant.
Circa 1966
Now I think I've got!
