Thanks guys. Its a lot of fun making stuff like this. FYI I looked up DABICO and they have moved from Garden Grove. However the brochures from companies like that are a wealth of information about the hatches, lights, panels etc you find on a runway, both civilian and military.
HVH it's hard for me to tell what scale it is...approx 1/24. I took the photo from the plane window and based on the width of painted lines in the area etc I took a guess and kept it in proportion. The real dimensions are 1" x 3/4" (around the size of a quarter dollar)
