Happy to help!
I'm posting the links to both of the sites I mentioned above. The SPO link shows change up numbers (to cross reference with the Viking part number for instance) as well as an incomplete list of machines that use the bobbin, and the SC link shows a different list of machines supported, including some viking machines.
This was part of the fun I went through when I was looking for bobbins for the 115

Interestingly, I've been told the Pfaff 6122 I have here can use L type bobbins, so I wonder if I don't have to be so careful with the Pfaff and Juki Bobbins that often end up side by side and confuse me.
