I can tell you that it's not any sort of cutlass I've seen in nearly 40 years of collecting swords. The hand guard looks similar to a US Model 1850 foot officer's sword, but the blade should be about 28 inches.

I could probably tell you more if you had some close-up pictures of the sword, but at this point - if I had to guess - I'd say it was a regulation sword that was cut down for wear by a child. This sort of thing was not at all uncommon in 18th and 19th century Europe.

The scabbard is the type generally used on a cavalry saber. Cutlasses almost always have leather scabbards with a single stud near the throat for use with a belt frog.

And one other thing...Bearhunter referred to a "bezel". I've never heard that term used in reference to a sword. What is it?
