I'm pretty sure that Glen over on the VSS reported having used the 15 bobbin. I know it's not an exact match, but what is important is if it will fit in the bobbin case and spin freely.
Now - Standard had the older "slim" version and the newer "stout" version. I believe yours is the slim. The bobbin cases for the two are different and I think the 15 bobbin may only fit in the older one. I'd suggest trying it and see.
The OEM bobbins for the two are slightly different, but I was able to swap them between machines - the bobbin cases are not interchangeable.
