Something I've always wanted to know, what is a musketoon?
This is an 1858 Enfield Artillery Musketoon, in .577 calibre. It was made chiefly at the government armory in Enfield, England. The musketoon was sighted to 800 yards. The Musketoon was considerably smaller than its sister, the Enfield rifle, measuring about 40 inches long.
I guess it was the equivalent of the carbine in it's day.
