    Looks like you got the best results from what was inside the bottle.  Just kidding...
   I was just looking at one of Otto's letters that was posted by one of the guys here,  it showed the reverse of your scope shots. His peeks looked like yours but were all negative spikes.  I think that it might be any important point, negative spikes, as also negative resistance in the coils.  He may have been onto something, if we can finished what he started. He showed that tuning is a very fine art, and can not be done haphazardly.

Hi Bill
Was that goldmine?
Its smetimes ahrd to find a great post after you read it becuase so many are added afterwards.
thanks
Scott

Long time ago cars used to be +ve earth. This meant the + side of the battery was connected to the body and the rest of the electrical system was connected to the 0 of the battery. I did a bit of research on that and one of the things I discovered was that you would get a netter spark that way. I suspect it has ro do with earth and the ionosphere being a capacitor.

Otto must have realised the same. This may be why his wave forms are mirror of yours.

   Masterplaster and All:
   I had received several PMs from Otto, with some of his circuit information. He lived in the same city as my relatives. My father was from the same country,  and my grandfather and I also have same first name as Tesla. 
   We disscused the negative spikes, and negative coil resistance, as also the benefits of using copper wire that has been tinned.  His devices did work differently. They remind me of Keely's use of implosion, or cavitation, similar to the way a Vortex works.  As a positive force towards the center, instead of an outward force that is dissipated into space.
    When a pulse is applied to a coil, that causes a negative spike, the re-action therefrom causes positive electrical generation.   
  I wish I knew more, but I do remember these observations that Otto had made.     I still miss him... 

   @ All:  Check out this U.S. company that also sells the Big  ferrite toroids: 10.000 permeability, and 12.000 induction

I am sure Otto would love you to share with the world his citcuit information.
We exchanged PMs several times and I have great respect for him.
