G. 4 Excelsior the G. I am almost certain is for 1937. I believe the warrior was probably G.9so I guess the G. 4 is the norsman .I did see one in the UK many years ago, I think he was in a museum called sparkford however where this was I have no idea except it is somewhere in the south of England warrior and norsman H.O.V it must be remembered that Excelsior 2 strokes as well. Prior to the second world war, I'm sorry if this is a bit peculiar I'm doing it microphone that is supposed to understand what I say, I have dates about this. As you can see
