Default Re: Help me please identifying antique engraving contraption, pantograph, ellipsograp

a very interesting item. with no marks, it could be a prototype of sorts by the inventor, or sponsoring company that may have expressed an interest in manufacturing it. i'd really enjoy seeing just what this thing does. i wish you luck in finding out.
after a better look-- two equally sized "tables". one side may have held a "master" design that by transfer, may reproduce on the other side. 1 : 1, perhaps with changeable ratios. just a guess. there are router based duplicator machines that do this, but without the complexity seen here.
