Later period figures could have shako reduced in height for forage caps. Remove cap peaks. IM 133 to 138 for Camel Corps, but shell jackets need lengthening to represent tunics. IME 7 and 8 are limbers and crews. IM 88 to 93 could perhaps also be used if required in fighting positions.
Numbers required in any event are small, rendering conversions less onerous.
Peaks may need to be removed from some caps. Officers could also include. As for 1st Bengal Regt. Horses IM H 1 to 4. Horses SK H 6 to 8 if shabraques are required for officers.
