Both my 1978 Peugeot PY 10 CP and 1980 Peugeot Pro 10, both team issue bikes, were made with Reynolds 531 SL (you could order 753 if you wanted). I believe the tubeset came out around '78 and was a response to Columbus SL. Reynolds introduced "Continental Oval" fork blades with the 531 SL that were a fatter oval shape like Columbus fork blades. The Reynolds tubing stickers on the Peugeot were in French and I remember reading at the time that Peugeot was the largest user of Reynolds tubing in the world.
