Direct clamp stems were common in the 1930s and 1940s among the
French constructeurs. See the "Image Archive" of the Vintage Bicycle
Quarterly web page

Difference to today: The steerer was threaded, and the stem did not hold the headset preload. Usually, a smaller diameter tube was brazed into the steerer. The stem clamped onto this tube.
You are right, Mick, not much new these days.
The next Vintage Bicycle Quarterly will feature a lovely 1940s women's Barra with a welded aluminum frame. Incredible and incredibly light. Barra started making aluminum bikes in the mid-1930s. A history of Barra (by Raymond Henry) was published in Cycle History 12, available from Van der Plas. Worth reading!
