Sid Smith's ESL speaker

I received a call from Ijaz to go pick up a piece of equipment from Sid Smith's son in law in New Haven, CT.  Many years ago Sid built an electrostatic speaker and I was to get the wire bending machine he built to make the stators.  Below are some pictures of the machine and what it was used for.

Apparently a successor to this speaker was shown by Joe Grado at the 1968 Philadelphia Audio Show and in today's dollar it would have been a $5700.  It is unclear whether that id for a single or a pair but even at double it is still a fraction of what the market commands today.
