Very interesting, and glassware, even an accomplished glassmaker would have
to work hard to reproduce many of these tubes!
thanks, brian f.

Hey all,
We just received some wonderful books from Spain regarding the Tesla Coils
of Monico Sanchez, an inventor that lived in New York a while in the
19-teens.

The experiments and Geissler/Crookes tubes are fascinating.  There is also a
section of Tesla phosphorescent lamps, and even a single filament lamp and
selection of "Tesla" tubes.  Highly interesting catalogue!

Sanchez patented a very efficient small Pancake Coil for X-Ray use that used
the "kicking coil" concept:

I built one of these a few years ago, and it is surprisingly efficient for
its size.  A small 4" coil .75" tall embedded in wax and rosin will give a
5 - 6" spark without any problems.  Note in the patent the specs - it uses a
.4 mfd condenser!

A huge thanks to Juan Pablo for sending these articles and photos.
