I think this variant of the 375 Plus is a bit closer (no two alike...pretend the road lamps aren't there). Note the slightly extended snout/smaller grill and the deeper-appearing (almost oval) headlamp placement...no marker lights, and the front valance comes up higher at the tires, like Earl's pic. Note Earl's pic shows a pronounced hump for the tank, and the engine vents on the side of the fender.
