 I hadn't realised that they were
printed on aluminium. Ouch!. I also
 don't know how they are fixed to the plastic header panel, my plastic
 panel is 'empty' and I don't see any adhesive residue. Maybe some
 kind of double-sided tape? 
 No, the aluminum is adhesive-backed (with a rather
potent adhesive).
 It's similar to what you see in serial number plates on machinery.  I
 have somewhere a PDP-11 banner plate by itself, with the wax paper
 backing covering the adhesive still in place.  If your plastic bracket is
 clean looking, it may never have had the panel stuck to it in the first
 place. 
  Odd...The chap who gave me the rack removed the panel (and the fan,
 and the stabiliser feet) for transport and gave me a box with them in. He
 commented that as I was putting a PDP8e in it, I'd probably not want the
 banner that was there (I am pretty sure that the original contents of this
 H960 was some kind of PDP11 system).
 Anyway, spend the day cleaning dust off parts, stripping the fan and power
 controller, etc. I did not notice any adhesive residue on the plastic header
 panel. And I think I would have done.
 So perhaps the header was blank, or the banner just pushed in (perhaps
 somebody forgot to remove the backing paper...).

Sounds like the banner plate for my 11T (Qbus 11 in a 50inch rack) the
banner holder was such that it could slid in from the end if you took
off the plastic end stop.  It has the PDP-11 in in the older reds scheme
on thin maybe .040" aluminium.
