British Colonial

 

HaT Set 8210 British Colonial Artillery in 1/72nd scale.

The US Army had several units that wore this kind of helmet from about 1870 to around 1900.

So while these are British, I will likely use them as US Army.

The gun is similar to the US 1895 mountain gun.

There is a also an older muzzle loading mountain gun in US service similar to this one.
