Carefully measure the diameter of the axle. I may have a tapered axle for you if you can live with a titanium one! The untapered axle setup will not hold up to much use. We machined tapered axles at the shop I worked at to solve the problems. The BB is not threaded except on the very earliest Lamberts, which had a conventional BB. Another BB solution is the Edco eccentric or the Mavic which do not depend on threads. I do not think threading to Italian is a good idea as the shell is not very thick if I remember.
The first derailleurs I remember were steel Suntour copies which resulted in a lawsuit. Suntour ferociously protected the slant pantograph until the patent expired. On that issue, does anyone know if the Nivex works at a slant? It looks like it might in the Data Book.
