Like this maybe: http://www.ak6dn.com/stuff/1174.jpg
This is a 'true' 11/74 panel from the never-production variation of the 11/74,
Not just a relabeled/recolored 11/70 panel. Note the additional LEDs on the
right hand side.
AFAIK no front panel exists that mates with this plexiglass.
I also have a complete DEC DataSystem-570 panel (frame, plex, switches) which is
a standard 11/70 panel, but recolored in light blue / dark blue / gray color
