I will take a more careful look at it, maybe disassembling and
taking some pictures.

I have put some more pictures at my site (taken from the material as
it was received. No cleaning or organization yet):

There are pictures of the plate capacitors:

That strange effluve device:

And some others if you look at the directory:

I will take better pictures when the devices are clean.
 
That Tesla coil has a secondary wound over a thick cardboard tube,
with what appears to be #22 wire insulated with black silk or cotton.
The bottom of the secondary is connected to a metallic bar that
extends below the support. The upper end is fixed to a pin that
crosses the tube wall. The upper terminal is a thick metal tube 
crossing a metal ball, supported by a wooden base that caps the coil.
The ball is connected through a hole in the center of this support
to a short wire that goes to the same pin where the coil ends.
The primary has a spring system to connect a tap to one of the turns.
I will take some pictures of the details soon.

I will take better pictures for that.

About the electrostatic machine, it is similar to this:

And, partially disassembled, can be seen here:

The restoration is going well. I am now fighting with some screws
that don't come loose in the support structure, and will soon
see what can I do with the old Siemens motor that powers the
machine.
