Sansui TU-9900 tuner face/dial window replacement part, new

Description

This auction is for a brand new window which fits the face/dial of the magnificant Sansui TU-9900 tuner.
There are the required holes precut in it to fit through the knob shafts through it so it's ready to install.
It is in new condition and perfectly clear (photos look white/opaque because the protective film is still applied to it).
I bought this some time ago for my TU-9900 but ended up not needing it.
It appears to be made of acrylic (not glass) but I don't know the material type with certainty.
