tom, jack, fred, et al... 753 was a MATERIAL, not a tube set. The material was produced in many guages in all the typical-of-the-era diameters and shapes. The same was/is true for 531. (And Tange Prestige, for that matter). Most consumers would be familiar with the products from all the old ads showing a box 'o pipes with the Reynolds logos all over it. Few builders actually bought the pre-packaged sets as shown in the ads and catalog tear sheets. Most bought their tubes in the guages appropriate for the job at hand. Thus, 753 'could' be heavier than 531, depending on the choices made. The material's characteristics were different and you didn't have to have ''The Knowledge''*** unless you were buying the 753 pipes. The lightest, thinnest 531 was similar to its 753 counterpart. Rule Brittania!! e-RICHIE, shopworn ***anyone get the reference?
