That is a neat looking machine.
I'd want to make sure the cams fit the machine, since most of the other attachments are for a differnt type of White machine. Seen that many, many times, a vintage machine with vintage attachments that didn't go together.
The bottonholer and the top clamp attachments won't fit - does anyone know if that is the correct manual/
I think sometimes this happens because a person got a new machine, and the accessories for the old one ended up with the accessories for the new one. I've found this most often in cabinet models - with all sorts of goodies in the drawers.
