Broken Zenith 2 carb

[wrndln]

I bought a broken Zenith 2 carburetor at a swap meet a year ago. I paid about $12 for it thinking at least the bottom section was probably usable. It has a broken flange where it bolts to the intake manifold as you can see in the pictures. It had crud all over it, so I couldn't tell its condition, even what version of Zenith it was. I beadblasted it a few days ago and it looks pretty good. I am wondering if the broken off flange can be reattached in some manner or the top section is hopeless and is scrap. If anyone has any constructive comments as far as whether the top can be save, I would appreciate it.
