Aluminum angles that support high temperature tiles around the edge of the Space Shuttle nose cap.
Artifacts are different versions of the same assembly.
Insulation, filler pad and adhesive still attached.
Insulation is scorched in some areas from reentry heating.
Although not so documented, these items are certainly flown.
Tiles would be bonded to the green colored, riveted aluminum surface using red Room Temperature Vulcanizing (RTV) rubber. Remnants of the RTV can be seen on the outer surfaces.
NASA photo below shows the nose area where these would be installed.

NASA photo (enlarged view)
of the nose area of the Space Shuttle Endeavour, with nose cap removed. Several tiles and lower peripheral tile supports are also removed.
The artifacts are similar to the peripheral tile supports shown in the photo (with white insulation pieces).
The artifacts would mount at bottom center, on the surface shown with a blue arrow.
