During WWII, metals like chromium and nickel were in high demand for the war effort and restricted for civilian use. Singer adapted by using a chemical black oxide treatment (similar to bluing or Parkerizing used on firearms) to create a durable, non-reflective black finish. These Blackside parts are highly collectible and tell a unique story of wartime adaptation.\u003c\/p\u003e\u003ch4\u003eWhat the Bobbin Winder Thread Guide Does\u003c\/h4\u003e\u003cp\u003eThis small metal bracket is essential for proper bobbin winding.
