Hi, you have done a great job with your restoration. And a bike with a long history in your country. Even has the carrier at the back, and the right color.
To Pollock, it came in black, & something like polychromatic grey or beige (?), which looks to be the color on 1KCBC's bike, but in the ads and catalogs at the time it often looked more like gold\bronze
