This ratchet has Husky Ratchet No. 1 and 2 patent numbers forged into the handle. On the opposing side, Husky Corporation Kenosha WIS Made in USA is forged. Since it bears the name "Husky Corporation" and Kenosha, we can assume this was produced in or after 1929.
45-tooth round head ratchet made by New Britain for Husky. This ratchet has the patent pending stamp for the QR button which was filed in 1972 and awarded in 1973, dating this ratchet to that timeframe.
