Those look like the Greist attachments that I have. You need another attachment to fit them on. You can get the attachment for either a short shank or long shank. I found the attachments on ebay but didn't buy one. I have a whole box of Greist attachments that were given to me. You had another pic with the same kind of Greist attachments.
