Airhead BMW R100 R80 /6 /7 Front brake lever perch with top plate and throttle friction adjusting assembly. Taken from 50,000 mile 1977 100/7  bike owned from near new by me when bike was converted to handlebar master cylinder. Never crashed, all screw threads good and screws not corroded Body paint is original and OK (see pics), top plate was repainted some years ago from bare metal with zinc primer and Simonize Tough (Tuff?) Paint which is a good match for the original finish and has prove durable.

Note. Don't forget the little steel wedge that clamps the assembly (not included). Failure to use one may cause the casting to break. (Hope you haven't found this out the hard way).
