I looked it up, and it looks like it takes class 15 bobbins. I don't know this model at all but the bobbin cases are usually a general standard on these machines, It needs a more accurate identification to be absolutely sure. If you have another bobbin case from a class 15 machine, you can try and insert it, then carefully turn the hand wheel by hand and see what happens. As you know, the bobbin case has a finger, it's usually either pointing lef or right (eleven o'clock or one o'clock), if you look at the part where you insert the bobbin case you should be able to identify which it is.
It's a very cool looking machine, it looks very solid and sturdy too. With a bit of luck someone who uses this model will post first hand information :- )
