Technical What bumper is this??

I've been trying to find out what these bumpers go on. Any suggestions would be great. If it's off of something important, I'd hate to modify it for my truck.

 

I'm gonna say '27 Buick but I can't make out the raised detail on any Buick pictures to confirm they match your bumpers. Best guess effort though.

 

That looks close for the rear, but each of the bars have that contour.
I am assuming a 20's or 30's luxury car??
I haven't found many with the split front 3 bar. It's got me stumped.

 

Got it!
one is a 1929 Buick roadster rear with spare tire. (the arched one)
The other looks to be a 1928 Buick regular car with spare tire. (the rounder one)
Thanks for the reply, it steered me in the right direction.
I can't get the 1928 picture to download
