The chainstay bridge is nothing special just a generic thing that was used by many framebuilders. Reynolds 525 tubing is a chrome-moly whereas 531 is a chrome-manganese - to the rider it probably makes little difference. The primary reason for it existence is its ability to be tig welded, thus producing lower cost for the framebuilder..
