Those blue ano'd Reflex rims are certainly a (blue and) silver lining here - stunning effect.
This one was always a favourite of mine; shame to see some components taking scars from the pavement, glad to know it's all coming back together (albeit a little bit different) and that rider was unscathed.
I enjoy the documentation of your progress in remedying the situation piece by piece.
Taking the time to 'fix' the saddle even though it's being taken out of circulation due to concern for structural integrity exemplifies a certain spirit. The actual process looks a lot like repairing chipped canvas Micarta.
