Can you help to identify these frames, bikes or parts?

The sturmey archer hub is a 3 Speed AW. Wipe a bit more dirt off and it should have a date stamped in..

650A is an unusual wheel size for the UK I think, it's more common in France.
Actually according to Sheldon 650A is very common on old English 3 speeds..

Thats some fast editing :)
It is a french standard though.
