Alex Singer has used internal expander seatposts since the early 1950s.

I don't know about Sablières, but already in the 1950s, André Marcadier did anneal his aluminum frames. The two shown in our book "The Golden Age of Handbuilt Bicycles" have lasted quite well, and André Marcadier claims to have had hardly any frame failures.

The frames of Nicola Barra, on the other hand, appear to have a more mixed reputation. They either failed early or lasted a long time.
