I have no idea what kind of linkage or slides may have been used, but
this drawer-full of roll transport and stack is a very new idea to me,
and very intriguing.  I realize you are not interested in creating in-
trigues but in finding a solution.  So, if all else fails, it may be
possible to reverse-engineer the movement, if you can give precise
measurements of all the relevant elements which remain.  Even smudge
directions on the nearby parts can help, of course.  I hope, as you do,
that you will find a ready-made solution first.
