The 1st Balooch, later Jacob's Rifles, were ferocious soldiers using modern technology and skirmishing tactics alongside the fighting styles they were raised with to become a formidable force.
The sword is a standard 1850's piquet weight Rifle officer's sword with an incredible blade bearing the engraved regimental name. The guard has been blackened and the grip has some wear.
The swords maker's mark is quite faded with the only readable part being the end of the name "...nning". The location appears to say "LITTLE BRITAIN" which I assume to mean a residency or British quarter of Jacobabad.
This sword can be yours for £750 or best offer.
