Now dismantled. Never worked — not constructed correctly! Never made an impact in real life either!

Hi!

Is this the “spontan” transmission designed by the Swedish inventor Fredrik Ljungström?

If it is, could you send me the drawings or pictures you made it from (and a description of it, if you have it)?

I’m very interested in how it was working — the principle. I have one simple drawing of it, but it’s not good enough to understand how it works.

I work on seamless transmissions, and I make prototypes of new ideas I get, and I need inspiration sometimes, and this is exciting.

If you could send me the drawings /pictures/description by email, that would be great.

Thanks.
