Excellent Condition! There is a grind mark on the case but no engravings or other markings on the sockets. One socket is a 13/16" which seems to differ from 20.6mm shown in the layout sticker.  However after consulting with Snap On, we learned that 13/16" was the convertible size size in inches and that this kit was sold with this set.  Snap On no longer sells the SM20.6 socket, but you can still find them on eBay if you'd like to buy one.
