pre-WW2 motorcycle IDs needed

[Dave Page]

Hi,
the first image appears to be a 1918 or 1919 Indian.
2. Harleys.
3. WW1 combination
4. cannot define
5. Harley
6. Assorted but with European style handlebars.
7. Harley combination.
8. Sidecar looks like the British type used on Norton big 4.
9. look more like Harleys.
10. German? Of real interest is the armoured car behind (Vickers protruding).
11. look very much like Indian 640Bs.
12. It is British, Norton perhaps?
It is very difficult with such grainy images.
Good luck,
Dave
