I noticed the real Engine doesn't have the two lights on the grill! But on the Code-3 piece has a Red and Green light on the grill, I thought the Red and Green we're a Chicago trade mark???

Also notice the real rig has a very different rear light package--like FDNY rigs. The model has 2 rotators. I'm hoping C3 corrects both these details b/c as far as I'm concerned the model is sh*t if they don't capture those details.

Well, after Code 3's Chicago E92 F-Liner, Orange County E65 got a custom grille and so did Fort Worth E7. Balto County E5, however, did not (grille taken over from Chicago E92).
I don't know about the JD engine as I don't have the model. It should have two red _round_ lights in the grille.

Speaking of LACo F-Liner: remember Ventura ALF engine's front bumper guessing game? It wasn't known until the end if C3 had changed it to the short type, so there is hope for a plain grille.
