In previous post I had mentioned the 'straight saber' (pallasche) of Arab/Ottoman form as known in Anglo-Egyptian condominium Egypt.
Here is a photo of one from some years ago I saw. It seems remarkably like the one worn by Zebyr Pasha on horseback.
Next is an Indian pata I have had for over 40 years which has interesting history of its own from my acquisition of it (saving that for memoirs
Here is the 'style' of brass work I mentioned with reference to the hilt of my saber (OP). Of further and compelling interest is the blade, which appears to be European with astral motif and remarkably like those found of course in kaskara.
The possibilities of this unusual combination are intriguing, and well illustrate the colonial confluences of the last quarter of 19th c. Great Britain.
