Yeah the gap...
unfortunately, the model was from Airfix, and Airfix isn't well known for it's high quality models...the gap, along with some other manufacturer mistakes I couldn't hide...
For instance, the bottom fuselage doesn't seem to really join together.
The .50 machine guns for the waists looked awfull, so I scrap-built 2 of them.
I used 2 machine guns left over from an other modell, I cutted hundreds and hundreds of small pieces of metal wire, representing bullets and glued em onto a strap of paper representing the bullet belt
Also the waist-gunners compartiment hadn't got any detail, so I made some bulkheads, walk-path and fuselage ribs from paper.
