GM Accessory Grille Guard or Aftermarket?

I picked this up in a pile of parts at an auction a couple of weeks ago. I have spent some time looking at some of the GM accessory grille guards offered and some of the aftermarket ones, but so far have not found this exact one. Most of the GM grille guards have hidden bolts, which makes me think this one is aftermarket, but want to make sure. Is this grille guard a GM accessory or an aftermarket accessory? Thanks Rod

 

Looks like one for a 46-48 Chevrolet/Pontiac.

 

Thanks, looked different than the ones I thought it might be. Simular to a coulpe other than the side profiles of the posts and most I seen had the bolts integral inside the posts not through them. Thanks Rod

 

that is definitely an aftermarket grille guard .

 

Thanks, that confirms my thoughts on it. Rod

 

one more vote for aftermarket.

 

I've sold a few of them grille guards and its definitely aftemarket.
