Could be Euro only, but maybe also Canadien.
Although 531 tubing wasn't so special anymore by that time, it was still a mark of good quality, and definitely above the mid level 501 tubing that was Peugeot's "standard" mid level bike frame tubing at that time, starting from the mid-80's.......
The best thing going for this frame, IMO, other than Peugeot's frame geometry that will surely give a great ride, is the fact that it's still a fully lugged frame, when a lot of mass production steel and aluminum frames from that time, we're starting to go lugless. Does not always mean the frame 8s stronger than a lugless frame, but it certainly makes this steel frame look much nicer than plain looking lugless frames.....
