This old double edge, razor blade scraper, was probably 10 cents when new, if that! But, I found it yesterday for a quater, and it cleaned up like new, and works great! The head rotates to 5 different positions, and I got a box of new/old blades with it to boot! It has a pat. No. of 2141565, and was designed for "McGill Metal Products Co.", of Chicago in 1938, by H.A. Stillson. The Acorn trademark, and the McGill Company is a first time hearing of this company for me.
