The reality is this. It is next to impossible to describe a definitive RGS profile. There were numerous options available and most Rocket Gold Stars were built to order, by that I mean because of all of the different options that were listed a prospective buyer could specify which options his machine was to be fitted with, and it is quite likely that no two machines would have left the factory with exactly the same spec. The BMS Gold Star book incorporates an RGS section with a detailed options list. (April 1962 Parts Service Bulletin No G21 A10 Rocket Gold Star) this contains a list of all of the available options. There are no less than four pages, and certainly far to many to replicate here! In the U.K.the RGS was available as a tourer or in full clubmans spec, and anything else between. Some had rear set foot rests, some had normal foot rests, the RGS is a rivet counters nightmare. Siamese pipes were the norm and they were fitted with a silencer that looked like a standard A10 unit, however the internals were quite different. Twin pipes were an option, as was the "track" silencer. There was the option of steel or ally petrol tanks, and wheel rims, and there were other options for the American market. To attempt to argue about the Rocket Gold Star specification (other than the frame which was unique) is next to impossible because there were so many options available you cannot say with absolute certainty what might or might not have been specified by the original customer. The subject is even more complex due to the fact that the original RGS was not a BSA model. The original Rocket Gold Stars were built to customer order and specification by Eddie Dowe a Gold Star specialist dealer in Banbury Oxfordshire. These original Rocket Goldies were Super Rockets with some Gold Star bits fitted, and some Eddie Dowe fabricated parts fitted. The Dowe Rocket Goldies would have had an A10 frame that was modified by Dowe, because that is what the Super Rocket model was produced with and therefore would not have followed the BSA RGS frame numbering sequence. So not all Rocket Gold Stars can be verified by the DA10R frame identifier, because not all Rocket Gold Stars were built by BSA. In fact it could be argued that the only genuine RGS models are the Eddie Dowe models because without the Dowe RGS it is likely that there would have been no BSA RGS.
