Chuck,
Well I cut a section of the clear vinyl or plastic outer casing off of a piece of the Campagnolo, yes Campagnolo derail casing, and it looks identical to the uncovered "stainless" casing, except for being a slightly smaller diameter. Both casing pieces are is in fact the same round, not flat wound stock. Will be happy to send you photos to prove it to you if you care to see it.
Here is the eBay auction address where you can also view the Campagnolo covered casing I purchased and used on my Hurlow. Certainly appears that in fact Campy made the covered casing (or it was made under contract for them).
Pulled a section of authentic Campagnolo, yes Campagnolo uncovered derail casing (i.e., the rear derail section), and a magnet does in fact stick to it, and the section of covered or coated casing. I'm not a metallurgist, but I don't think all stainless steel is non-ferrous===believe it all depends on the alloy content, thus a magnet will stick to some more than others. Try a magnet of some of your stainless steel spokes, and you will most likely see that it does attract or stick.
No disrespect intended, but I personally like the covered casing on my Hurlow, and that's what is important to me. If you don't like it, no problem, just really don't care to discuss it any more. To each his or her own. I really like riding my bikes a lot more than talking about them.
Thanks again for going to the trouble of expressing your opinion about my bicycle.
