Airfix Mossie

The two parts are the forward and rear gun supports. When fitted under the guns, the two spars will fit over the 4 tiny triangles moulded on the inside of the nose area. They are a real pain to fit and it is very important to take the utmost care, otherwise the gun barrels will not line up with the holes in the nose cone. I am in the middle of the same build and most of it has gone well, but the kit is a real test of patience. Hope this helps.

I can check for you tonight when I get home. I have a cut-away drawing of the Mosquito listing all parts.
