Will be looking at my normal 1/48 build too (may be on the drag with my F4G to finish and the 1/72 Tonka, plus a couple of cheeky work deployments to fit in around a family holiday!)
Have not built any Gulf aircraft, so nows the time.
Am thinking of ZD790 or ZD851 as I have the decals.
I could place ALARM missiles onto AJ as I have an Airfix 1/48 F3 that has them in the stash!
Some great Gulf War Pics here

Sprues have now been washed - will source 2 pilots gor my normal in flight finish (maybe from the Airfix GR4 in the stash!)
