British pattern Infantry sword....please help

[katana]

I found information on the 'horn' ...it seems that it is a French horn adopted by the 51st Yorkshire Light Infantry after Waterloo, later to include 105th in India.

"The Kings Own Yorkshire Light Infantry (51st 105th Regiments of Foot)

The 51st Regiment of Foot was raised in 1755 within the West Riding of Yorkshire and has been associated with this area ever since. In 1839 the East India Company raised a new Regiment the Second Madras Light Infantry.

After the Indian Mutiny of 1857 this Regiment was re-designated as the 105th Foot (Madras Light Infantry).

The Cardwell reforms of 1881 saw the 51st 105th Regiments of Foot amalgamated to form The Kings Own Light Infantry (South Yorkshire Regiment)"
