Description
Made of wood and plastic, this is a VERY RARE item. Made by the famous FABER CASTELL, this ruler appears to allow the user to calculate energy and distance, using various Logarithms. Named on one side, the center section extends outwards for precise calculations. Could also be used for engineering purposes? There is some light wear and scratches, but all markings and increments are easy to read. Also has a prominent Waffenamt on the reverse. I have NEVER seen another one of its type, making it VERY RARE! A UNIQUE item, it would make a PERFECT addition for any collection or display!!
