ID this 57 Chrysler Trim Piece

I'm trying to figure out what 57 Chrysler Model / Models this trim piece was used on and where it went on the car (Grill, Trunk, Rear Quarter). I do not think it was from a 300 Model as Pictures I have looked at of 300s all seem to have 300 on them. I looked at a lot of Chrysler Car pictures on line and could not spot this piece. Its about 3 feet long.

sorry, 1957 buick...........

 

Yep, '57 Buick. Probably the one for the grille, since I believe the one on the deck lid states which model the car is -

 

Thanks, a couple of guys ***ured me it was a Chrysler part, and the 57 300 models use that same red/white/blue in a circle design. No wonder I couldn't find it looking at 57 Chrysler Pix. Doh'
