Sidearm of some kind?

Thanks for the reply
I am aware of the french artillery sword but this one is a single edged sword (I forgot to mention in my first post)
It has some ball point pen markings (possibly from a repair job) on the wooden part of the scabbard, when the leather is removed. The sword has this hallmark on blade and at the end of the grip.

Correction - The sword has this makers mark on blade and at the end of the grip.

There is a chance this is a Yeomanry sidearm from mid to late 1800s
after doing some more research I found some images on google that suggests a crown being part of yeomanry symbolism and the Y, of course, meaning "Yeomanry" (maybe). If you type Yeomanry in to google images you get a lot of Crowns and and the letter Y.
It is possible that this sword is from Australia or New Zealand (Canterbury Yeomanry Cavalry??).

I would do some more but it's late and I'm getting tired.
I hope someone else takes an interest because I don't see myself solving this one alone.
Thanks for all the replies so far!
