I'm impressed by the aerodynamic mod to the single headlight, and the horn. The v shaped radiator might have been for this reason, or to simply increase the surface area for cooling, over what can be achieved with the same height and width flat radiator
I love finding the dealership tags on the dashboards, very rare
