The “high transparency” mesh I described in my earlier posts is 81% open or transparent. Both the wire size and the mesh dimensions are very close to the prototype, but in HO scale. See: https://www.twpinc.com/wire-mesh-material/stainless-steel/80-mesh-stainless-high-transparency-0012.

Yes, I’ve looked at it. I also attended Kristen’s presentation. To me the suggested wire mesh seems about 30% transparent, vs. perhaps 90-plus% for the real poultry cars.I’ve also worked with similar real mesh. It sure does NOT look like the mesh as seen on the real poultry cars. This is undoubtedly due to lighting effects, as the mesh’s dimensions seem close to correct. I suspect a good part of this is due to both lighting angle and diffraction.
The problem here is that a real item shrunk to 1/87 of it’s original size would NOT look “right” … the physics of light do not allow it.
