The attachment manual I have from 1907 shows this set - in the drawer molded insert. I have the set for both the back clamp 66 and the side clamp 27.
The manual I have from 1912 shows the 66-1 Red Eye back clamp with the next generation attachments.
I also have a 66-1 Lotus manual, but it is missing the front cover so I don't know the date - it also shows the drawer with the above set of attachments.
Those three are both oversize manuals with a separate Attachment book.
The one I have from 1913 is the smaller, green style manual that has the attachment instructions in the back.
