Yes and No. From the original production, there is no S-Planar with white mount. However, it is not impossible.
In the last few years, when one takes his S-Planar or any other lenses with the old black rear mount back to Kyocera to service, the technicans will likely change it to a new white mount.
The same happened to my 35/1.4 AEG. I just asked for CLA, but then when I get it back, the rear mount changed from black into white. My old black mount sees some wearing and lost of paints, so I do not mind a new white one as replacement. Furthermore, the lens is for my own use and I do not plan to sell it, so it does not matter at all. The photo quality will not be affected anyway.
So to answer yoru question : Yes, the lenses must have been serviced, so cannot say it is original. No, he lenses with white mount may be good instead of bad.
