Question: Model Holley carburetor?

[Jack64]

Attempting to determine what model Holley carburetor is on my 1964 Corvette, 327/365 HP. I believe it might be a 2818...
I am planning to replace the problematic automatic choke.

Unit was installed in 1972 to replace original carb.
Numbers on float bowls are 4094 & 4099
Choke shield shows number 3849804

Any help is appreciated

Jack - based on numbers you provide indicates a 2818 on 64/65 vette

Thanks C5vetter.
I strongly suspected it was a model 2818 Holley
