Rick had suggested in his original post that the card had something to do with the 68th Punjabis (which regiment, by the way, mutinied at Bareilly on 31 May 1857, and was not re-raised). It was unusual, but a few NCOs may on occasion have been attached to Indian infantry regiments by the end of the 19th century, most commonly in a training or educational role (teaching English, for example). Most tasks, Indian personnel could perform quite well for themselves. Attachments to what artillery that was allowed to exist in the Indian army was more common, as such technical knowledge was denied to Indians after 1857. I have never seen enlisted personnel so attached in any regiment. My guess is that this information on the MIC (and these are usually muddy enough to begin with, even when presented large enough to read) is simply a reference to the voume, page, and line in the original rolls where the award of his medal is given. The reverses, uncopied, have details on where the medal was sent. I think parts of these original rolls are now at the NA and it may be worth checking it, but if all you have is his hat and not his medal(s), it probably won't be worth the effort unless you are already at Kew for some other reason. (I am, by the way not "anti-British"; I am merely anti-imperialist and opposed to many of the ideas that came along with that system.)
