I've got a Reynolds 653 frame, and I know 'technically' it comprises a mixture of 753 stays and 531 main tubes, but I was wondering...what are the forks made out of? Would they be 753? Or 531? And the 531 main triangle. Is it regular 531c or something thinner like 531Pro? And how is it all stuck together - 753 needs to be silver soldered at a different temperature to brazing, so where the 531 and 753 tubes meet (at the bottom bracket/seat stays) how does that work? Is the whole lot silver soldered?
653 is what Reynolds called a"concept tubeset", and you're correct about the main tubes being 531p, the rear triangle in 753 and fork in 531c.
Although I have known all manner of mixes with the 653 label, but the above is the most common. As the tubes themselves aren't brazed together, they're mitred and rely on the accuracy of the mitreing and lugwork to fix them: the 753 tubes will certainly be silvered into their respective lugs but the others may or may not be (silvered that is).
That's my understanding, hope it helps.
N.B a great deal of mythology surrounds 753 but that'll be going off topic.
