This is an old set, but it's new to me.
It's the British Sailors and Marines set from HaT. They are Napoleonic era, and I don't do Napoleonics. But I plan on swapping up some of the heads with the Gardner Gun set flat hats so they can be US Navy sailors for the post- Civil War era.
Some of the gun crew will become Texans and find themselves at the Alamo. I will probably add a few big hats to them for the hot Texas sun.
