Hello Barry, What does it mean? Well the early EW only has RG which I can only presume is R 350 cc and G gearbox now the improved gearbox with the RGC with sliding on rails I presume that this was the third attempt at success. This gear box was also used on the B29 model with I believe the same RGC. The difference in internals I have explained previously. Now for the 600 cc models W is the prefix and G for gear box I and there is WGT I think but that is getting away from your query. regards Alan
