Dave,
Maybe it's the lack of coffee in the bloodstream, but I can't wrap my mind
around what you might have and where this goove is. A 2x3 roll back should
look very similar to an RB Mamiya back, but with an enlarged mounting area
so that it reaches the sliders on a 4x5 graflok back. I don't know of any
roll back that would take a ground glass, Is it possible you are thinking of
the goove that would have held the darkslide?

The Ysarex is a late model tessar formula, nice lens.  don't know much about
the tele xenar

Kes  ahh make that Les.  gotta get some coffee
