Hot Rods Updated :help : Identify Grille Shell

Picked this grille shell up at an auction today. Its a big shell, Im guessing big truck or car ? Anyone know what it's from?

 

Throwing out a guess of 1931 Dodge 1 1/2 ton

 

Calling '31 Dodger .... Mr. Dodger, line 3, please ...

 

Got a side view and maybe a height dimension?

 

Does not look Dodge to me.

 

We can rule out Rickenbacker. Bob

 

Grille is 40 inches tall, 25 inches wide.
