Reynolds 531 is the name of a set of tubes that manufacturers can make a bicycle out of. It's not a frame that one could make an "exact copy of".
You are almost certainly correct in supposing that bike's not made from 531, however. It's probably a hi-tensile steel frame of some sort. Looks pretty nice except the saddle, though.
