Internally brazed, lugless construction, Carbolite 103 frame tubing and the stamped steel but windowed rear dropouts points towards something like a Peugeot PH10 or PH12....from maybe around 1983.....
It was at the top of their lower end model line. A pretty nice bike at that level with the cool fully chromed fork and very good hadling and ride from its then already well known Peugeot excellent frame geometry.
