I'm not sure what Weber called them, but it looks like the one Holley built under liscence and called it a 5200. Weber may have called it the same thing...
They were used on just about every four banger and some six cyls that Ford, and just about everyone else, built up to the late seventies or early eighties. I used to build up Capris and Pintos back in the day, so I've seen a few 5200s....

Great little carbs, for what they were. I have a book about those things somewhere, I'll try to dig it out...
