I didn't look at the baffles.
The early bikes had no number pipes, no relief for the brake pedal .....those do.. (not sure on 300,s).
The heat shield, black looks glossy, KO were grey, no gloss.
Edit, I think I was in error on the shield, it's not color, it's the chrome finish, early ones look blasted then chromed , i.e. duller finish.
