Interesting in as well interesting, lol. The video popped up in my recommendations, so no to owning or ever seeing it before. But many features make me consider it a possible work of Herb Bedell. I once asked him how many he made and he said over 130, and his son commented at least that many and I saw many made afterwards.
Herb was also prone to make engines on a "bet you couldn't" basis and the wobbler would be just that kind of engine. Did you also think it looked "Herbish"
