The Curta is perfect.
The only thing: I never had replaced some of the metal parts with plastic parts (as for the later variations of the Curtas).
Today a mechanical calculating machine wouldn't developed, I think...
Or maybe Tatjana J. van Vark could develope a Curta based calculator...

A reproduction would be nice - you will need all drawings (you recently asked for this...) AND the know how (material, production, specific calibration, lubrication, tools and machines...)
So I think a small series would not be payable...
