Long time ago I bought a mechanical ink-stamper (for lack of better name) with which you can stamp things 1, 2, 3, ...
Long gone are the instructions.
Brand is LION, item C-71.
Any idea how to reset the numbers to 000001? (000000?).
By hand, individual wheel by wheel? (A pain -- seem to turn in only one direction, so if you go one too far, you have to go all the way around again.)
Any automatic way of doing it?
