If I may, it looks as if the captions of the two black and white photos contained in the April 22nd, 2025 message were inadvertently reversed by the staff of the French magazine La Vie aérienne.
The flying machine identified as the aviette Baleck appears to be the voilier of Dr. J. Cousin, and vice versa, a hypotheses seemingly confirmed by the following image, lifted from the same issue of La Vie aérienne, which shows the pilot of the aviette Baleck, January.
Oddly enough, in the May 4th, 1922 issue of the French magazine Sciences et Voyages, Baleck and January are referred to as Bolbeck and Janvier.
