   I have a Delrin space bar blank you can have.  I made some
of these on a CNC mill when I was restoring a Model 15.
It doesn't have the screw holes; you'll need to drill and tap those.
If you can't find one ready to attach, let me know.

   The plastic space bar used on the older models dries out and cracks.
That's one of the few plastic parts on a Model 15.

   Teletype part number 74720, Screw, Thumb.  Don't have any of
those; I just checked.  But thumbscrews can be ordered commercially.
Looks like a 1/4-28 bolt, 3/4" long.  (Teletypes are mostly National
Fine Thread, so it's probably 28TPI, not 24, which is coarse.)
You can easily get a bolt and washer that will work, until you
can source the correct thumbscrew.

   Any glass shop and most hardware stores can cut rectangular
glass for you.  Or you can use polycarbonate with anti-
scratch coating, which is cheap in small sizes.
