Thanks but I assume that your strategy is based on the assumption that the manufacturer is known, keeps records of frames . The manufacturer is unknown so serial number is useless AFAIK. I'm hoping there is a more direct accurate method such as markings on tubes.
might photos discriminate between many choices (BRANDS: Reynolds, Columbus, to name a few and then many choices of their respective tube types) of tubes? Surely, they cannot
