I have the same machine from looks like the same company (Emblem in ATL) I found this post by coincidence - looking for bobbin case info. Did you ever get your machine figured out? I just wanted mine for topstitching purses and sewing some leather bags. Haven’t done much more than a try out as I needed a bobbin winder (cant get the one on it to make a nice tight bobbin of thread) so I just got an electric one. Anywho, would love to hear your experience!
