If we stick with the topic. It is a rehilted khyber. Thoose are not rare at all. In the anglo afgan war, brittains employed indian sepoys for fighting the afgans. Think about some looted tulwar, wich hilt was used for rehilting a khyber blade. I can immagine that this was done frequently during thoose years. Take a look at page 243 of Tirri's book.
