There was a series of small booklets on the yeomanry cavalry by L.Barlow and R.J.Smith with illustrations by Bob Marrion. I have No 2 the North Somerset Yeomanry. The illustrations show them with the sabretache worn by officers throughout the Victorian period. Not by other ranks, though. The booklets were: Sussex Yeomanry, North Somerset Yeomanry, Yorkshire Hussars, Westmoreland and Cumberland Yeomanry, 3rd count of London Sharpshooters, Duk of Lancaster's Own Yeomanry, Yorkshire Dragoons, Lovat Scouts and Scottish Horse, Warwickshire and Worcestershire yeomanry.
