Found this model on: www.paper-replika.com - where also other fine models can be found. It is the forrunner for the Y-Wing used by the Alliance in the fight with the first death-star. Consists of 3 sheets - and no instruction - so I searched for reference photos to be able to build. Here we go: Picture 2 and 3 - cockpit: Unfortunately I did not cut the space for R2D2 and neither the space for the cannoneer. This fact I noticed too late and therefore I had to cut R2D2 and the cannoneer cockpit later on.
