I don't see the 260 listed on thier site just 230 and 250. If you go to Vikings site, down at the bottom there will be a place to email hardware support, they should be able to tell you if you can still get them and where. I have the Viking #1 and it is different from the current Ruby and Diamond Deluxe (which bobbins are the same in) you can't use just any bobbin though. Normally Viking machines are grouped into categories, like the Viking #1 is in 1 and the Ruby and Diamond is in 7 so you would look for those numbers on the outside of the package to see if it fits but I don't see a 260 under any of the 7 categories.
