Richard, I think you are on the right lines although the stamped marks are the prefix and suffix of the carb basic number. The full number would be something like 772FKDA 9500 6BB where 9500 might be the basic number for a carb of any type. It is 36 years since I worked at Ford but I think the prefix is for a '72 model year Ford GB product and the suffix defines the changes ie the first would have been AA, a minor revision would be AB, a major revision BA and so on.
The throttle linkage bracket looks very much like Escort crossflow.
