We all know this trick, and have seen various versions of it. Rhett Bryson wrote a whole book about the many variations of this very visual effect. The effect has universal appeal (making money magically). And if you show this effect to laypeople, many are still fooled by it.
SS Adams had this nicely made small version in red plastic with wooden knobs and wood and cloth rollers from the 1950's to 1970's. The rollers have a surprisingly high capacity. Later models used plastic and vinyl for the knobs and rollers, and did not roll as far so had less capacity for changes.
This example is probably from the 1970's. The printer is in excellent condition -- no problems or damage. It has the original box, with some damage on the top flap (a small hole torn in one edge, but flap is still otherwise intact and closes tightly) Beside the damage to the top flap, the box is generally in good shape, with no missing flaps.
The instructions here are a photocopy of the original instruction sheet. The trick was issued from Adams with three blank pieces of paper that Adams -- only one of these original sheets is here now, and it is browned with age. (Easily replaced, of course)
This plastic and wood version that is getting increasingly hard to find, so here is a nice example for a serious collector.
