1860s British Expeditionary Force (Update 8/3: cavalry finished)

[Ray Rivers]

Great looking army! 

As a side note, does anyone have any idea what model of guns are depicted on the far ends of this 1864 photo? The guns I have should still be okay for 1868, but they don't seem to match any of the ones here, so I'm not sure about earlier scenarios.

Looking at the photo, the guns are almost certainly smooth bore cannons.

I'll drop a link here to a site entitled "Field Artillery of the British Army 1860 - 1960:"

Don't know how accurate it is, but if you look at the very bottom, it shows that, with the exception of the 12 pd Armstrong rifled breech loading artillery piece which was introduced in 1861, the British didn't really shift to rifled artillery until around 1871.

So I would guess you are looking at 8 and 12 pdr cannons in the photo.
