I learned that my machine was manufactured in 1917. I am still waiting on the new belt to arrive. There was actually a needle in the machine with 'white' stamped on the shaft. I still have to finish cleaning the shuttle, shuttle race and pressor foot. Then put it all back together. haven't polished the metal yet. I started to take off the face plate and clean in there. However, then I saw (I think on Treadle on) a tutorial about taking it off and that some part shifts when you remove it. So I got scared about my ability to put it back together and decided not to take the face plate off. I will just give it a good oiling.
