Enough, again.....
Here is what Flyjack posted.....
More Placard evidence..
I found a better image of the "placard",, also a pic of the 727 control panel Boeing decals.
The letters DO NOT not match the Boeing era font, note the "C" (more open), the "A" (sharp top) and the E (mid line length). The Placard has a different/newer font.
The font does not match Boeing 727 external decals either.
Conclusion,, based on this and the other facts it is extremely unlikely the "placard" came from NORJAK.
