Radiator shell ID?

Anyone recognize this shell? I've seen one like it before, but can't remember what it was from, if I ever knew for sure. Thanks

 

I'd guess Buick, but it's no more than a guess (Buick did have a notched corner at the top, but not as pronounced or as elegant as Packard).

 

it's a gm product...close as i can get

 

It is a 1928 Olds radiator shell.

 

Oldsmobile! That's it. Just did a google search and it appears to be a '26. All the '28 shells are more square looking. Thanks for the memory jog!
