History Another "What is it?" Thread

Hey guys, just bought these two grilles but can't ID the one in the back - thought it might be late '20's Pontiac or something. Went through my copy of the "Monstrous American Car Spotter's Guide 1920-1980" to no avail. Is it maybe european or some type of truck or commercial grille?



Thanks,
Steve

 

I think you should find the rest...1929 seems very similar as well

 

Whoa - Auburn?? Awesome!

Thanks,
Steve
