Cribbage's petit Difference Engine

tool
Description:

I dare not disassemble this item completely for fear it may not work again. I cannot resist tinkering with it though, in an attempt to better understand how it works.
I still cannot completely fathom how a machine which originally filled the space of a small cottage can have been reduced to fit in the space equivalent to a human head.
