Her is my current collection of old wooden rulers. Don't have as many as I should but I have to start somewhere. Staring at the top is a 18" Helix, 15" Amer MFG Concern made in Faconer, NY with plenty of advertising on it. 15" Westcott, 12" Westcott Typist Ruler, 12" no name but made in the US of AM, another 12" Westcott and at the bottom is a 12" K&E Co Star Quality 3 sided ruler. Just today I picked up a wooden 12" ruler and a metal 12" ruler, both Westcotts from K-Mart today. Both were made in China. A few of these old US made wooden rulers should be in your collection because we do not make them anymore. It is sad.
