Many thanks for your inputs; not sure the significance of Yathagan (apologies for my ignorance

but having now looked up the Werndl reference I can see many web entries for such things.... most interesting!
Does M1867 mean the year or just the model (or both)? I had assumed this would have been a WW1 piece..... would that be valid? Elsewhere on this website I've had a thread about a Russian Court Sword which turned out to be 1826-ish and I'm trying to see how this all fits into my family history.
I've also got a kukris but more on that later when I've had time to examine and photograph it !
