Hey, I thought you were joking! Apologies offered.
The sword I have is an Eastern European kilij-type with a Hungarian blade. Most likely, cossack.
They employed a variety of parts and styles. The most popular one was a kilij-type crossguard and they also used a karabela-type pattern.
Here are examples:

or the one with down-turned quillons, like that:

It needs to be brass.
If you have one, please send me pics and detailed measurements to:

Tons of thanks!
