Do you mean a kit of yourself, when did you want to arm it? I imagine you have made an excellent interior improvisation.
Yes Luis. It was the kit I bought many years ago at a flea market. I paid a 1$ or so at that time. The figures of the crew were made as the busts. I binned them. The model is about 40 years old now and I wasn't so skilled. Therefore I would make the model in different way if I started the one today.
Anyway, I had to make the entire cockpits from scratch although not to much info on that could be found here at that time. Also made from scratch the dorsal gun turret as there wasn't the part there too. The landing gear can be retracted and all legs were made from scratch. Both crew compartments had opened hatches for getting on. The ladder of the front compartment can be folded allowing to close the hatch. All antennas were made from scratch too. Additionally I made my decal for the plane name with the art of the spider and the red lines on tops.
And a couple more if you are interested...
