After years and lots of searching, I could finally find and buy a LP with Aurčle Nicolet playing some JS Bach works that are not common in his discography.
There is a beautiful and inspiring version of the trio sonata BWV1039. Also the interesting Partita in C minor BWV 997 and the sonatas BWV1028 and BWV1029
In this LP he plays with "Christian Nicolet". The booklet or explanatory sheet that normally came with LPs is misssing so I have no idea who this Christian Nicolet could be.
He plays much like Aurčle and it is strange that his name has vanished so soon.
