Hi, Many years ago when I was 20 years old a lady in Millville NJ gave me a really nice cromed metal protractor compass for making circles and curved lines. She told me she worked for many years at a company that made balsa wood planes and that`s what she had it for. Anyhow it came in a red & clear plastic sleeve with a few parts. On the clear side it has a name and the first letter is real fancy, Grainercy. On the flap that closes it, In small print that sticks up it says Westren Germany. I can not find any information on the name. Any help would be greatly appreciated.
