Identifying rifling types

[josquin]

This comes from the Ammo forum in a thread originally asking about Webley revolvers
but it ended up straying OT so I thought it might also be of interest here.

"sovereignright" posted this pic of some odd rifling types
which none of us could fully identify:

so I posted the pic on the British Militaria Forums under
Sporting Rifles and Other Old Guns and got this reply:

1. Alexander Henry
2. Enfield / Snider
3. Ezekiel Baker
4. W. E. Metford's later type marking the transition from muzzle to breech loading.
5. Ratchet rifling tried by more than one maker.
6. Jacobs
7. Whitworth
8. Lancaster's Oval Bore.

Not in the pic was the belted bore of the Brunswick Rifle (like #6 but with a single belt.)
