Incedentally, for those who wish to get a nice sharp photo, below is a photo of how I just photographed one of my NR derailers. You can also see that the resulting photo was quite yellowed - but some editing in Jasc Paint Shop Pro took care of that in the following photo.

I used a plastic shoebox lid for a backdrop. The flat-white backround works well as a nice backdrop that doesn't wrinkle or shine.

The derailer is being held up by a Presta valve cap under the upper pivot bolt.

Take care,
