Another carb identification

Alright now upon talking to Daytona Parts they need a number that starts with an R on the body of the carb which I don't have. He said its behind the throttle linkage and I may need to pull the throttle to view it, but all I have is one single capital A and blank space.

From the post I read above and the fact that Holley isn't stamped anywhere on this carb I should just assume I should be on the prowl for a new genuine Holley instead of trying to again rebuild this "reman'd" carb and have problems with it right away?
