Technical Help identify 6cyl manifolds w Carter WA-1 carb

This (and more stuff) was saved from going into the s**** metal. Anyone who recognizes it and knows if it's worth anything? I'm guessing it's from an american car, but being in Sweden there are other possibilities - but I wouldn't expect to see a Carter carb then.
I would tell you how it looks, but I can't really say anything you can't see for yourself in the pics. Feel free to ask though, I'll help you if I can.

 

There a tag on the carb? Numbers on it anywhere? I don't recognize the pattern but that doesn't mean much.

 

Yes, there is a br***(?) tag on it, I missed to add that pic in the original post. Sorry about that.

 

It's been a year, so I try again. Anyone who recognizes this?
