Here we have a complete Top Quality Drawing Set. I would guess from the early 70s maybe older. Made by the A&W Products, Co Inc, Port Jervis NY. Sold for $1.28 through K Mart. These sets are getting harder to find and even harder to find complete. This set included a metal compass, 6" ruler, two triangles and a protractor. All made in the US and one like it should be in your collection.
