Hello B.I
This picture from the India Office Library And Records, which I have post on this site before might be of interest to you. Armed knights in the service of the Raja of Samthar in Central India possibly 1870s? It is rather posed note the chakram round one chaps ankle, the armour looks real enough which seems a trade off between protection and mobility. To me it looks like it has a main function against slashing weapons but sure it would also deflect some stabbing thrusts. When I was a little boy my mother would take me to the museum at Sandhurst, you could just walk in those days, wonderful Indian collection which I believe is now in the Army museum Chelsea. Tim
