This is my grandfather's old slide-rule. Interesting, can anybody calculate with such type of instruments? Camera:Nikon D50 Lens:Nikkor AF-S DX 18-55mm f/3.5~5.6G ED Location:Birsk Image quality:RAW Cropped?:Yes	NIKON D50 1/200 sec f 7.1 55 mm Flash: Not Fired 18.0-55.0 mm f/3.5-5.6
+ Add comment Well, at school, we used these calculators, but I must admit, I don't remember how to use them now when I will get some into my fingers, I am sure knowledge will come back! I remember my father calculating with an addiator, find out, what this is: http://www.addiator.de/addiator-duplex-w-die.jpg Connie @ 2007-07-12 02:43:02
