This is an interesting discussion, and coincides strangely with a dream I had early this morning, in which I used the correct grease on a Norma I have been working on, but the grease performed strangely by having far too much viscosity the first couple of times I moved the shift bar and then far too little viscosity after it had "warmed up." It was an odd dream on a number of levels, and a strange co-incidence with this thread.
I'm the author of the Sinar Norma text and video CLA Guides, and I recommend using molybdenum disulfide grease as the primary lubricant for the moving parts on a Norma. Most of the lubricated surfaces in this camera require only a tiny amount of this grease, and in practice excessive lubricant only serves to collect dust or grit in places you don't want it accumulating. That said, I'd be very wary of using anything other than moly grease as a long-term solution for a Norma, or any other camera with finely machined mating surfaces (especially aluminum ones).
According to the best sources I have, the tub of grease that was included with new Sinar Normas was a molybdenum disulfide formulation.
I'm not kidding about the dream, BTW. Maybe it is possible to love Normas too much.
