I have only seen the tool kits in the tool roll as in Dicks picture. The tools contained within the kit do differ between the models, this is to fit the rear wheel spindle nut. The RB/RC kit contains a 24mm Eye Wrench which is replaced with a 27mm Eye wrench in the RD kit. As Dick has said there was also a pressure gauge which was a clock type gauge, these do again differ between the models according to the parts book. I believe the RB gauge had a silver face with 2 scales Kg/cm2 and PSI all writing is black. The RC/RD again had a silver face with 2 scales Kg/cm2 and PSI but this time the PSI scale is red.
