I've got several first pressing from Roadrunner - RoadRacer - R/C that have different catalogue numbers. Some are RR ****, some are RCD ****, and some are RRD ****.
The RR is for Roadrunner releases, the RRD is for RoadRacer, and the RCD is for R/C. The catalogue numbers had to match the "label". The "label" of release varies per country, because at that time the Roadrunner name was not liscensed worldwide. They had the RoadRacer and RC sub-labels for international releases because of that. Unless I'm mistaken (but I don't THINK I am) so long as there is no ****-2, you have a first pressing (the label will be regional).
