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.
How 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
Columbus often has a symbol on the fork steerer tube, and if Columbus SLX you'll see riflings in the seat and downtubes where they come into the BB. Tange steerers have 6 internal riflings, Columbus have 5 IIRC.
I useta work with framebuilders who could ID fork blades (Columbus are rounder) and seat and chainstays (by diameter and taper) but I lack that eye/memory.
Call me Mel. Some years ago- never mind how long precisely- having little or no money in my purse, and nothing particular to interest me at home, I thought I would ride about a little and see the other parts of the world. It is a way I have of driving off the spleen and regulating the circulation.
