The plastic of the pieces is in good shape from what I looked at it is fine structurally, and the clears are clear and the whites seem to only need cleaning. The rubber tires on the wheels seem to be fine (colorwise) although one seemed to be hardening (I did not check most). In reply to Collector245, I know for a fact that it is a Lego box because it was my brother's that he received as a gift in the late sixties. It had a big Lego label that you can see the edges of in the photo - the colours in the edge of the label match LEGO graphic style. I can only cite provenance that it is a LEGO box as it had a LEGO label (but now only the edges remain). I did see an image of a lego box that was same a couple years ago, but when I searched images recently there was not one that matched.
