Carburetors ID- What are these?

Inherited some old carburetors and need help to ID them. Anyone good at telling what they are from pictures?

 

Nobody jumped in so I’ll give it a shot.
First photo, Rochester 2G, and it looks like an end carb from a factory tri- power setup. Next is an Autolite, looks like a 2 barrel, so a 2100
Second photo, Rochester AA’s , used on ‘49-‘50 Oldsmobile and maybe others.
Third photo, ?, no idea.
Last photo, Autolite 4 bbl, a later design than the 4100, but I don’t have any idea of number. Last carb is a 4100 Autolite.

 

I think the first photo on the right is a 2150 and the last photo on the left is a 4300.

 

Why guess????

Most of them have tags. Read the number on the tag, and Google.

As Fordors mentioned, the second picture are the type AA used only (thankfully) on 1949-1950 Olds.

Third picture looks like a Carter BBD (Ball & Ball?) and a Carter WO.
