My KRL1003 came with a Snap On Fossil binder and with an owner's manual in it. I imagine they've been giving those out for years with new tool box purchases.
I bought a old Snap On box I think it was a KR59A? If I remember correctly it was dated 1969. It had this Little booklet in it dated 1970. Its wrinkled and a bit dirty but otherwise nice. The box was flawless.
I have a booklet similar to DandD's that is dated 1952...it now lives in its own drawer in the chest it presumably came in.
Many pictures of Snap-on craftsmen lovingly polishing the details and fitting the drawer slides.
