Hi, I have an RC and a now dismantled Nordwest both of the same year, the RC starter nose is just a direct mesh gear and the retaining nose is short. The nordy has a longer nose and housed in there, the end of the starter shaft, 1 gear and 6 pre loaded cup washers, odd spacers and those 2 dog gears like you discuss, so technically I have them, weather or not to part with them, I will have a think, because firsts and foremost is keeping the machines going but secondly are my future needs.
