Is there a model # (or list #) on it anywhere?

As long as the choke tower exists, there is a list number stamped into the tower facing the front of the car. For example, the common as dirt 600 vacuum carb usually has a list number of 1850-something, and the 750/780 vacuum secondary has a list 3310- something. hope this helps,

Try the Holley web site. Hard to believe perhaps, but plenty of great info there.

Here we go.
The numbers i found are on the Choke column (or however you call it)

List 4310
182

R-4310A


2300-G


1969 I.H.C., V-304 & V-345 Eng.
