Here is a short film from 1923 where appears a bicycle probably built by Fred Hellens on the velodrome of Herne Hill...
Henri Depierre, the Parisian manufacturer of Gemini bicycles, used recessed brake nuts as early as the mid-1970s. I suppose they were machined by himself, that was one of the details that distinguished these craftsmen from the prestige brands that produced in mass.

This NOS one was recently sold in Switzerland for 35 CHF, a bargain.

Thank you very much for your appreciation.
In France, we can regret that the notoriety of the great Parisian craftsmen leaves little room for talented regional builders like Jean Thirouard whose quality of work is not recognized at its fair value.
I don’t think Peugeot has ever used Durifort tubes.
The tubes were manufactured in its factories (light and extra-light) except for high-end models (hikers or race) built with Vitus until 1957 then Reynolds appeared in the 1959 catalog.
This one is probably a "touriste léger" PC40 of 1952...
Thanks!
The chainstays are relatively short (415 mm) especially for a touring bike.
This explains the detour taken by the light control cable through the seattube 😄

Whether it can be called vintage while it was built in 1993 and is equipped with brifters, the debate is open 😁
