A photo, no, sorry I don't. It's the same type of mesh you see covering the windows of a house or screen door. The one I got is made of plastic or vinyl. I will build the framing first and lay the screen mesh over it for the grated floor. I found in my 1/72 scale set I got a spare set of the FSS access arms for the LOX vent arm and Orbiter Access Arm. Did you get those with yours? What did you use for the curved pipes for the MLP?
Amazing work - such attention to detail. I've lurked this thread for a while, but all I do is marvel at the pictures
BTW, how far are you now with your STS-6 thread?
