Hello everyone. I have a question that I hope someone can help me with. I am working on a Singer Foot Controller from the 20's and opened it up and found this.

At first I thought that it was rust, but it doesn't seem to be. It feels like some sort of baked on substance almost like glass beads. I started to do research on it and found very little but I did see someone selling a part just like this and it looked the same. Is this normal? If not, is there a good replacement or some sort of retro-fit available? I like the foot controller and want to keep it with the machine if at all possible.
Any help on this would be greatly appreciated. Thanks.
