Dutchie,

I can see a vacuum secondary diaphragm operator hanging on the side of your carburetor. The older operators were cast in metal, the newer ones are molded in black plastic, I can't tell from the picture if that's a very dirty older operator, or one of the new black plastic versions. Most vacuum secondary Holleys come in either 600 cfm or 750 cfm ratings. Because yours has center hung fuel bowl floats, I'm going to "guess" it is a 750 cfm version, possibly the list number 3310.

As Doug alluded, there is a list number stamped on the front side of the choke horn, see the pic below.
