Does anyonre know what the thickess is?
0.7 mm. (That includes the paint layer.)
I also don't know how they are fixed to the
plastic header panel ..
Maybe some kind of double-sided tape?
One of mine (ca. 1970) has a sheet of double-sided tape which covers the
entire thing. (The glue on it appears to have hardened/failed, and the whole
works feel out of the plastic panel.)
