What model are these Rochester Carbs

What model are these Rochester Carbs? Anyone know? If is there anything to be aware of? I am considering to buy them and don't have much information on them other than they are freshly rebuilt. Any info would be great.

Thanks

 

pics?

 

I accidentally clicked submit before uploading the pics but here they are. THanks

 

I saw those on craigslist. I dont know about the spray on chrome...lol. anyway those are the small base 2bbl. They would fit on most 3x2 intakes.

 

I remember reading specs for those in the invisible Delco book.

 

and they look to be the 2G models. They should have the script right on the top.
