Does my interpretation of Marx's jigsaw puzzle throw out the pieces (passages 
of text) that Gil cites regarding value being determined by labor-time
 required for production?  No.  Since total value equals total price, the
 value of constant capital, which enters into the determination of the
 value of products, is a sum of required labor-time despite the fact that
 the value of the constant capital can differ from the value of means of
 production.  Marx strongly implies just this on p. 265 of Vol. III, Vintage.
Now, Gil and others may disagree with this interpretation, but that's 
another matter.  Believe me:  I read the same text as you do, but interpret
 the instructions differently.  That's why the results differ, not because
 I chuck out pieces.
