There were many different kinds of 531 tubesets. There was a straight gauge 531 called 531 tubing; for more information on some of the 531 tubesets go here:

There was also not listed in the web site above 531st for touring, 531t for tandem, 531os for oversize tubing, 531cs for custom sport, 531pro which was similar to 531c. The lightest weight tubing was the c and pro followed by the cs.
The weight difference between the regular butted and regular dble butted was maybe 1/2 pound.
