I have been trying to find details of this aircraft myself, and sent an e-mail to the National Technical Museum in Prague.
This is their reply:
Sir,
we have lot of photos in our archive but only those Anatras which served in Czechoslovak Air Force. And in Czechoslovak Air Force flew Anatras unarmed. That´s why we can not help you.
We have in our archive and collection many photos of our unique item – sole preserved plane Anatra Anasal in world. But we can not simply send you photos of interior or details because we would like to avoid any commercial misusing of these photos. We can send you some photos which you need but only under condition that you conclude agreement on this matter with us.
Don´t hesitate to contact me in case any question
Best regards
