your picture does not show the "important" part. It's class 15, easy enough, but it is left or right hook.
though just about all except Singer is this way
So you need to look at that little notch at the top
Oh wait, your machine missing that part, you need a bit more than just the bobbin case.
You need these pieces to make this machine work. Though these are Singer, but you get the idea. Yours has the swing clips to hold the retainer in place, so you'll need to look for that style retainer, Singer had a different type (it's the lower middle piece with the screw)
your best bet will be to check out goodwill and thrift for a machine with the bobbin assembly similar to yours that has the parts - and swap them out. It does not have to have the same name on the front, and may even look very different on the top side, but that won't matter as long as these parts fit.
