There are some folks that love old or older machines on this site and they will likely be the ones who can answer your question. You may want to re-post with a different title so those machine aficionados can find you easier. Even just the name of your machine would cue them in that you are looking for a part for your machine.
Glad to have you here. Lots to see and enjoy and so much help from unexpected places and from folks who are at every stage of sewing skill from beginners to experts.
