The internal fuselage strut is made by welded chromo-molibdenum steel tubes of slightly oval section.
The rear fuselage has a wooden structure covered by birchwood layers.
It is connected to the tubes frame by bolts (see n.3).
The metallic attachments are fixed to the wood by plates with two lines of bolts.
On the upper plates, the bolts heads (just behind the sliding hood) are covered by an aerodynamic plate.

On the mid and aft fuselage structure of welded steel tubes, we see some shaped structures with small holes. They are for installing aluminium alloy external panels fixed by Dzus-type locks. 
The central part of wing was made of aluminium alloys, integral with the fuselage.
The tube structure of the fuselage was connected to the alluminium alloy wing by bolts.
