The year was 1975 when I was browsing small dusty workshop located next to the garage within our house backyard. It was perfect combination, I was about to turn 7 years old, eager to explore the darkest corner of my childhood realm and the dark workshop was the most mysterious chamber in our entire family estate, no bigger than four cubic meters occupied with heavy and old greenish oak cabinet with couple of drawers and compartments filled with tons of different tools, mechanical devices and various interesting stuff I didn't know their origin and purpose. It was, more or less, the year when I started to break things in order to find out what was inside or to find how something works, foolishly believing that I would be perfectly able to put things together back. Well, from this point of view in time, I can't remember if there was at least one mechanical device I "inspected" in such manner that I successfully restored after unscrewing all the bolts and junctures...
