I used to cast the Ornithopter for Tobi. I know he was looking to sell the range a few years back, and I know he did sell the Orni' on as he told me, and the buyer approached me to arrange sending him the masters, and any surviving moulds.
I've had a search through my email and sorry to say I can't find a single reference to it, so can't share any hard, fast, or useful details. I'm pretty certain the buyer was German, and had bought more than one of the range.
I'd suggest asking on German forums or FB groups.
