Here is a vintage Snap On tools KRA-281 3/8” drive socket metal case. This measures approximately 19 1/2”x 6”x 1 1/4”.

This originally contained a full assortment of sockets and a full assortment of Extension bars, ratchets, speed brace etc. Has the kind of wear you would expect for its age. Have taken lots of pictures. Please study the pictures carefully to help gauge condition, these form part of the description. Thanks.
