It took a few minutes, but now I see the lion's face, but at the same time where it's eyes and nose are located, there looks to be three numbers, like 543.
Considering the nickname CIGAR, it could be a caricature that is smoking, as the bottom right corner has something going on there?
There seems to have been some deliberate thought put into the outline around whatever it is. Almost resembles the shapes of the flower petals of their cap badge?
As you can see, am entertaining all ideas since it does not make sense to have that particular warning stencil at the front of the vehicle (thank you Dave).
