Subject: [CR]Features Needed to Identify a Frame/Bicycle ?

Ahoy !

What features should be photographed to aid in identifying and showing a frame&fork or bicycle to make it easy as possible for fellow listers to scrutinize and perhaps, provide information ?

Understood is that any single photograph may show multiple features and that some features may be dead give-aways. Example: Single photog. showing seat lug, binder bolt treatment, seat stay joint.

Below is the list of features that is intended to be the comprehensive compilation (which can proabably all be captured in a handful of photogs. and, most of which is certainly beyond my skills). Comments, corrections of descriptions, additions or deletions ?
