You bet Wing!
Interesting example, and these hilts invariably had the oval cartouche which as you have noted typically had the Royal cypher, mostly of course of Victoria Regina (VR), but also many variations like these with the symbolic baton and sword, some with regimental devices etc.
As Gene has noted it appears the officers full name is shown and if you contact the National Army Museum in London, they have archived records of officers and personnel which might give you service details.
All the best,
Jim
