Here's another oddity in German colors. Not '46, not made in Germany.

Never seen that. What is it ??

Seems to be of something like 'delta-canard' configuration.

Payen Pa.22 Flechair, French 1940 race prototype. There was supposed to be a pulsejet version of the same thing.

Payen also worked on several military applications of the same basic concept but the war stopped it all.
