Tom, I have one of those ER cases for a camera with a MOOLY, but am not sure whether it's for a short or diecast body. If it's for the short body, I find it rather odd that the transmission arm would be just squeezed in there between the leather case and the body. But, when I try to put this black MOOLY setup in, the screw on the bottom doesn't line up with the tripod mounting hole on the bottom, so maybe it's for a short body.
I took the beast out for a test ride today and it performed flawlessly. Had a post war 50 f/3.5 Elmar with a VALOO hood, as well as my sweet Mountain Elmar. What a combo! (Of course, the whole thing was lost on my wife, as she foolishly didn't realize the historical importance of the occasion as she walked beside me. For some other strange reason, she didn't seem to care.....but that's beside the point)
As far as the Mooly sound goes, this is the closest I can offer you:

I did it on NPR as part of a weeklong series on 'gadgets'. Hope I don't sound too much like a doofus.
Enjoy!
