Great old set.

And the box seems to be in decent shape too. I find the random parts occasionally, but usually not the boxes.
I still kick myself for not buying a brand-shiny-new set like yours years ago for a couple dollars at a local flea market. I thought parts were missing, and that the ratchet tool with the flat-head bit would only turn one way - it didn't occur to me that you take the bit out and install it on the other side to change the ratchet direction.

(NOT one of my proudest moments.)
