I've seen them used as portables on a table as well as on those large frames. I don't think it has to be 15 even if they are a favorite. The models aren't all the same, hook, race, bobbin case set up are different even between horizontally as well as vertically set bobbin models.

Either way, you are onto it and the proof is in the pudding.
