Wow! I haven't seen one of those in YEARS. I actually had a "pocket"
version of one. It was incredible. I'm thinking it was made by
Britannic, but I could be wrong. I bought it at a yard sale about 35
years ago and probably threw it away when it quit working a few years
later. Everything inside was was either tin or white metal. Instead of
the crank, it had a rotating knob. Mine had two fixed decimal places
(just a painted dot) and maybe five digits.
