Peugeot boasted in the 80's with a decal on many of their upper level frames that their upper level frames were "Brais a le main" (Hand Brazed).
In Peugeot's case, at least in the mid 80's, unfrotunately, it didn't mean high quality as I had to go through quite a few examples (must have been at least 6 to 8 bikes two trips) in a dealer's show room to find my PSV that had a good, clean brazing job and well finished lug points. The other frames had ugly brazing gaps and splatter, lug points that were cut off, blunted or were filed uneven from one side to the other, and I even had a head tube start buckling on the first example I took home after a couple of months of riding because I and the dealer suspect, brazing overheating must have damaged the headtube steel. I was lucky they replaced that first bike under waranty.
Yes, hand made, but I guess not all those frame builders in the Peugeot factory were that skilled. Frankly, the mid level Schwinns ("robot" brazed frames) that were just coming out at that time, were so much cleaner/better made. "Hand made" can only be good if the hands doing it are trained well to do it. I guess Peugeot was pinching pennies like crazy back then with their brazers and assemblers....
