Jean, Gene or Gean?

AMG called him Jean Oslo, but I don't think he did any films.  This AMG photo is from the early 1980s,  Later that decade he posed for Old Reliable as Gean.  During that same period he also did a few solo films for other studios 

I'm trying to find my collection of Gene pics from his last visit to OR in 1994.  Gene had matured into one helluva a DILF.
