In his New Year’s greetings, Mr Jean-Pierre Desroches drew my attention to the two versions of the F-AKEK medical aircraft, I quote:
“I would like to take this opportunity to show you a small detail that you may have already noticed concerning the Joustra F AKEK sanitary or Red Cross aircraft, depending on the name. Mine is a simplified version,

identical to the first sketch of the civilian F AKEK that can be found in the catalogue of a department store reproduced in Frédéric Marchand’s book.

Marchand, 2001 – JEUX ET JOUETS DU CIEL p.29
there are no passengers windows under the cockpit windows.

1935, painted sheet metal, clockwork mechanism rolls on the ground, the central propeller rotates 60 x 59 cm
is identical to the one shown in Leonard’s book and to the second sketch’s version in the department store catalogue.

Marchand, 2001 – JEUX ET JOUETS DU CIEL p .29
It has windos under the cockpit.
These aircraft were released in 1935, with the F AKEK medical versions coming out a few months before the civilian versions. “
