I can't remember for sure, but I believe it is a front loading rotary machine...
Easy to tell; look at the area where the bobbin goes while turning the hand wheel several rotations.
- If the shuttle (moving bits) goes all the way around continuously it is a rotary machine. You need a bobbin case for a "front load rotary" machine.
- If the shuttle (moving bits) go back and forth like a top load washing machine, it is a oscillating shuttle machine. You need a bobbin case for a "front load oscillation shuttle" machine.
My best advice however is for you to bring the machine to a repair shop so they can give you the proper bobbin case.
