Guns,
The F-100 D (single seat) was fitted with four 20 mm guns, mounted in the lower fuse, just under and forward of the cockpit. (The F model, two seater, had only two guns). The only externally visible part of these guns is the tips of the barrels, located at the rear of four recesses in the forward fuse skin.
The BVM mould has the recesses nicely replicated, but without the gun barrels,
To replicate this I made some gun barrels using, two sizes of ali tube, and short lengths of both 4 & 6mm fuel tube.
These were glued into the gun recesses, and “Bobs yer Uncle,” Guns on board..
At the finishing stage, I painted in the dark gun panels using BVM metal coat, and then added weathering/gun blast residue, using an air brush and some very thin charcoal paint.. The Viet Nam Huns got pretty dirty in this area.
Note how I have tried to create a “sloppy” repainted look with a blurring of the camo green on the paint line. This is scale for 63 -163..
