I have a couple of '69 carbs restored by Eric Jackson and I have considerably more than that tied up in each of them.

It should not have the cast in rear accelerator pump squirted boss. It looks like a later carb to me.

Agree.
Your air horn stamping says December 1969,but that secondary squirter boss on the main body says after February 1970 according to Eric,here...

Suggests someone took a later main body and stamped an earlier date on the outside air horn.

Definitely a later carb. This is not the first I have heard of re-stamps and hokey carburetors coming out of Competition Carbs of LI NY

It appears the baseplate is a later one also. It's too thick between the secondary shaft and where the throttle bracker bolts.

The base is actually a service unit for a 1966 carb (3246/3247/3613)--note the accelerator pump lever is the type with the slide-in stud instead of the screw-in stud.
