=================================================================
I could not resist to buy this  VINTAGE POCKET-VOLT-METER I found
in a CA.-FleaMarket. It is a memory from my childhood: When I was
5 years old, I completed my first engineering project, a battery-
powered light for my scooter: In a »PRINCE ALBERT« tobacco can a
4.5 V Flat-Battery under the board, cables to the lamp on front,
and cables to the ON/OFF-Switch on the handle-bar ! Our neighbor,
a retired mining engineer, was so impressed, that he gave me his
POCKET-VOLT-METER: "You will have a use for it ... !" 

impressum:
