Going to post a few additional Holley 3-BBL pictures today and see if people can recognize the carbs and the differences.

Hints: In the First Picture you can see that the carb is a Holley 3-BBL carb.
You can also see that it has the typical 4 bolt cover for the Secondary Vacuum Diaphragm to open the single Rear Barrel.
You can see that it is a 1050 carb vs a 950 cfm carb because it has "Tube Nozzles" vs "Rear Boosters".
The carb also has the 50cc Accelerator Pump Arm and for sure the 50cc Pump Housing and Diaphragm

Hint: In the second Picture you can see the "Extended "Primary Accelerator Pump "Shooter" Nozzle.
You can also see the "Cable Driven" Choke Plate on the carb and the other parts normally used on a Manual Choke Carb.

Hint: 3rd Picture you can see the 50cc Pump Housing and Diaphragm. The 3-BBL rear Throttle Plate and the Rear Race Bowl without
machining for an Accelerator Pump.

Hint: In the Last Picture you can see the carb is not a 1050 cfm carb but is a 950 cfm carb (4 normal boosters).

What DID I NOT TELL YOU (based on the pics in today's thread?)

Just a tip for those that might be rebuilding one of these. These vacuum diaphrams are larger than a typical holley 4-barrel. They happen to be the same size used on the 67-69 tri-power Corvette setup, for those looking for one.
