Rick Pargeter wrote about rebuilding a Pratt-Read stack.

Rick, I rebuilt a Pratt-Read last year.  I removed very thin and supple
zephyr skin, which feels almost like onionskin paper, but thinner.  PPCo
supplied me with new zephyr skin, but it didn't stick to the wood very
well when I hot glued it.  Also, it was difficult to lay down properly
without a jig, which I am told (by Durrell Armstrong) was used during
manufacturing.  I ended up with individual circular leather pouches from
PPCo.  The player works well.

I did seal the pouch leather with a 50/50 mixture of Carter's rubber
cement and a thinner (Carter's also, I think).  Also, I made a little
circular jig to press each pouch in place.  I stuffed a piece of wood
dowel into a rubber bellows tube, letting it protrude just enough to form
the pouch to the proper depth.  The diameter of the rubber tube is about
the same as the leather pouch.  The edge of the protruding wood dowel was
rounded to that it wouldn't cut the pouches.  Good Luck.
