Beautiful bike! It clearly got lots of love it's entire life. You will always have a clash of styles putting a utilitarian accessory on a racer-styled bike, but your rack seems well made and largely follows the lines of the bike. I do wonder if bending up the flat rear "carrier" section of the frame to match the lines of the forward section of the rack and the cowl, seat, and tank would encourage a racier look, and I dont think it'd hurt the rack's function. Could a tubing bender do the job without harming the chrome? Or, maybe better, also replace the chrome with gloss black powercoat: it would cost nearly nothing (£20 or less?), unlike going the other direction, from powdercoat to chrome, which would cost 10x the amount (ask me how I know!). It would be great to see some pictures of the bike around town once you are allowed again. Here in the US (at least in my area of Southern California) thankfully there are no restrictions on street riding. Good riding!
