So, Dave and I are getting to the point where we're about to start mounting up
our indicator panels, but we're not sure what some of the mechanical details
(below) are.
Could someone who has one please take a look and let us know (or, even better,
send us photos)?
It appears that the bezel and inlay mount to the rack with the same kind of
'ball on post' (BoP) mounting things used for blank panels.
What we can't quite make out is how the Belenex light shield, and the circuit
board with the bulbs on it, mount to the rack. I suspect it's totally
independent from the mounting of the BoP mounting devices for the bezel/inlay,
but....
The one mechanical drawing we have (RF11 engineering drawings, pg. 186) does
have cross-sections, which confirm the board is mounted to the Benelex on
stand-offs, and that the Benelex is somehow thrust up into the bezel, but
exactly how the Benelex is mounted is not clear to me. The mention of a "Mtg
Bkt Benelex" suggests that's mounted to the rack with brackets, but...
Help!? Thanks (hopefully :-)!

I have one or two of these indicator panels (missing cables, IIRC).
I will dig them out and see what I can get. Mine arrived already
de-installed, so I have no idea what they looked like on the rack. I
can at least get details of where the mounting points are.

If someone can't get to mounted ones, I can trundle over to CHM artifact storage
and look at one of our racks.
I would think LCM should have some readily accessable, though.

It looks to be fairly straightforward; the plastic "ball on post" brackets
are mounted to the rack rails, and there are metal brackets that screw into
the BOP brackets that hold the PCB/lamp assembly.
Hope this is the right assembly for you, if not, or if you have questions,
let me know and I can try to fill in the holes...

I am not sure if it is what you need, but Vince S did some 3d print STL
files for some of the ball mounting gizmos.

Those pictures are just what we were looking for.? That's pretty close
to what we thought but I wouldn't have guessed that the metal brackets
to the PCB/lamp assembly screwed to the ball-on-post brackets rather
than directly to the rack rails.
Thanks,
Dave

Those look like what I have.
