Hi ...

For those in the SF Bay area there is a very nicely built
coil at Frys Electronics new store at 680 and Automall
Pky ( formerly Durham Rd. ) in Fremont. Entrance off of
Osgoode. If you talk to a salesman they'll get someone
to turn it on for you.

I guess it was built to emphasize historical accuracy over
raw performance .

The secondary is conical, about 3 feet in diameter at the
bottom, and a foot or so at the top, wound with around
300 turns of quite heavy space wound wire. A foot above
the top is a copper sphere also about a foot in diameter
with two discharge points arranged diametrically opposite
each other.

Primary is 2 inch or so copper strip, nicely polished, as is
the capacitor - gap - coil connections. Seems to be tapped
around turn four.

The gap is a really pretty rotary driven by a cogged belt
from a motor hidden underneath.

It's in a Faraday cage made from heavy chain link and built
into a gazebo.

Makes fairly strong connected arcs to the chain link probably
4 feet away, easily visible in the well lit store. The inside of
the gazebo is black, which helps.

When a keyswitch is turned it starts up a little while later
for a few seconds (10 or 15 or so).The  guy who had the
key didn't know who made it, but the workmanship is superb.
Someone put a lot of time on  this one.
