Identifying a bayonet

I am trying to identify a bayonet I acquired from my great uncle some years ago. He was my father's uncle and, after he died, my father got it along with a few other items. I expressed interest in it and my father has kept it until recently, when I brought it home. I intent to display it. I have been looking online to find information on it based on the markings but have been unsuccessful. The blade is about 22 3/4 inches long. It has a "trojan or spartan" warrior head stamped into the ricasso (term I just learned) and a number 8 on the muzzle ring. Can anyone help me using the photos below?

Thanks in advance.

Please disreagrd. I found it. It is the Pattern 1860 Sword Bayonet (Yataghan).

The Pattern 1860 Sword Bayonet is another example of an existing bayonet being modified for use with the Martini-Henry. At the time of the Martini's adoption, there were large numbers of these bayonets in stores, so in the interest of saving money, they were inexpensively modified to fit the M-H. Their muzzle rings were bushed to fit the M-H barrel, and the tops of the pommels were filed down to allow the Pattern '60 to slide onto the top barrel band tab. This bayonet does not have an integrated saw like the Elcho, but features a curved blade known as a "Yataghan" type blade. It is very common to hear these generically referred to as Yataghan Sword Bayonets.

Overall Length: 28.1 inches

Blade Length: 22.7 inches

Well, maybe I haven't found exactly what I have. Now, I am seeing that it could be back to 1856/8...it could be Australian, British, etc. It could be civil war era. I am hoping someone can help me based on the markings. I would like to know positively what I have.

Thanks, old-smithy. I appreciate the information. So, more than likely, this is a civil war-era bayonet? Wow...I did not think it was that old. I'm extremely pleased!
