Please refer to the image--the set includes everything you see. $50 takes everything plus a heavy duty toolbox. I bought it at Sears in the mid-80s but it has been *barely used* over that time. The ratchets look brand new, the sockets are shiny. I would have marked it Like New condition except there are small patches of surface rusting on the 1/2" crank and on one of the long 1/2" extensions. Every other piece looks clean.
Both 1/2" and 3/8" drives, includes a ratchet and extensions, even a 1/2" drive crank. Each size drive comes with a set of English sockets and a set of Metric sockets. Four socket sets in all. Ranges: 1/4" - 3/4" and 10mm - 19mm. The 1/2" drive also comes with 13/16" and 7/8" sockets.
The tools come with a heavyweight two-level Craftsman toolbox. Also included are some miscellaneous sockets: various sized plug sockets, and some duplicate sockets. If you buy the set, you get it all.
