"Indian Mutiny- Bengal light cavalry question" Topic

Sources are hard to come by and often contradictory.
Most of the BLC regiments had orange facings on the collar and cuffs all with white piping around the collar, cuffs and on the back/arms/shoulders and around the hem of the shell jacket. Some references however show a narrow orange strip between the two white piping stripes on the chest, others don't. The miniatures I have clearly show three 'stripes' but before I start painting the middle one in orange I'd like to ask the collective knowledge base here. Also, officers have all the white supplanted by silver and definitely have no 'middle' stripe down the front. However, their dark blue Kilmarnock headgear is shown piped and braided in red or orange. ANy ideas? Thanks for any help!
