What is it? Is there a modern equivalent? Answered
This is from a 1949 Pfaff 332 sewing machine foot pedal. (I believe the machine was brought to the US by a war bride.) When I tried the machine recently, it wouldn't completely stop when I took my foot off. We opened it up and found this partially decomposed multi layered 'thing'. Other than dust and dirt, it looks like the only damaged part.
Does anyone know what it is? Does anyone know what a modern equivalent would be?
