RE: Arne Hende?
Arne contracts with various (mostly eastern European) suppliers who make engines to his specification. Often he uses more than one supplier to produce a complete engine, to avoid the problem of his supplier making extra copies and selling them behind his back. Arne's engines are always very high quality and very interesting.
I don't know Arne's current status. He has been ill with cancer and I haven't heard any recent news.
