Here are photos of two Produx Original calculators. Both have
green/clear vinyl slip cases and metal tipped, black plastic handled,
styli. I also have the instructions from both - these cover both
numerical and sterling calculators so I have two identical copies. Both
calculators are 6.5" x 3.4". They were made in West Germany, probably in
the 1960s. They are virtually identical except that one is sterling and
the other is decimal.
