vfrpilotpb, if your ever in doubt as to who your traffic is, the easiest and safest thing to do is ask us. No atco worth his (or her) salt would bite your head off. I would much rather you ask me to confirm your traffic than risk you lifting against the wrong traffic causing a loss of sep or worse in your case lifting into vortex wake and having you flip over (obviously this would not happen against a c152 but it could against a c130!). We often give the ac code as that is what we have in front of us on the flight strip.
