I've been trawling French cycling websites, surprise
I came across this site (All in French) that has a fantastic photo section that goes way back. If you don't know who Jean De Gribaldy is, Wiki site first.
This led me in a very roundabout, rabbit hole way to the site (All in French) below. Not really the subject of this thread as its racing, nonetheless a fascinating history with some beautiful bikes, some lovely details too. I liked the blog owners introduction, so its translated below.
An evolving blog created by Bernard Gougaud, a customer for over 20 years and Henry Wisniewski, a mechanic for 30 years.
Supplemented by other testimonials, with the agreement and help of Karine and Steve, Raymond Wolhauser's grandchildren.
Each and every one of us will only ever know what we know and, at the other end of the world, or on the same landing, there may always be someone (to whom, perhaps, we don't even say hello) who, in our favourite subject, knows something that we don't know, that we may never know... if we don't want to hear it.

"The workshop of Bernard Carré is a bit shrouded in mystery.

His custom frames found widespread attention when famous champions like Derrigade, Anquetil and Geminiani had their bikes built by Carré. And this fame allowed him to stay in the business until the 1980s. He also was responsible for some top class frames of other brands and even stepped in for André Bertin for a short time, when their manufacture was devastated by a fire.
