I looked up the NSN of the ND928 in the NATO MACRL but they are maked as obsolete (1959? or 1960 something?).
Rob's extra numbers may allow a better idea of whats out there, and availability. Especially globally. Thanks for your efforts.
I feel better than I did looking at the front end and wondering about a bearing, and if it was a 'show stopper'.
Thanks again to MLU
Ian
