There are a great many other British cavalry sets that I am afraid won't get made if we focus too much on the Zulu War. I need Hussars, RHA, and Yeomanry more than I need another box Zulu War cavalry.
Now, if you are proposing a box of British of cavalry wearing hussar style uniforms; with a selection of alternate heads wearing spiked helmets, pill boxes, and busbies; with separate sabers and carbines that can be attached as needed...
I would buy that set. I far more than I would of Natal volunteers.
