Even with the small photos & much of it being to dark & also in the shade you can see the dinged in petrol tank.
Still in the late 40s up to the 80s many a rider rode bikes with dinged in petrol tanks, exhaust systems, mudguards & such. The main thing was price & being able to ride. Most were looking at the rest of the bike being in good shape or a small change or two would make it ideal.
These days a scratch on the tank & so many want to have a new one & in some cases it would be better to have a NEW bike as they have a few months to a year on the present on with said scratch or small ding in the petrol tank.
Remember all the others on the road are crazy & out to kill you.
