Here is my late '67 CB77. Honda put chrome fenders on them partway through the last year of production 1967.
The frame has tabs for mounting rear turn signals, another late addition.
The black paint is all original, the engine side cases, and I think maybe the side covers have been repainted by a previous owner.
AFIAK, the exhaust is all-original as well.
I bought it with less than 2,700 miles on it several years ago. Because the mileage is so low, I only ride it 30-40 miles per year (few short, 10-15 mile rides) to keep that mileage low.
