Recommendations for British Mounted Yeomanry

[Duke Speedy of Leighton]

What ho chaps,
Am about to embark on a mad project, involving Lurkio Home Service British Infantry.
However, I also want to do the Shropshire Yeomanry, who wore Heavy Dragoon uniforms.
Crimean Heavy Dragons, with lengthened tunics have been suggested.
Does anyone have any suggestions for 15mm as Freokorps 15 and Eureka don't seem to do Crimean kit (and you all k ow my love of Essex)?
