That is a nice, older gunong as far as i can tell. It is small and has a somewhat straighter, less bulbous hilt. The silver work also looks older (and this does look like silver). Others may have better dates for you, but i would put it somewhere around 1900-1920s.
I hope you plan to clean this up a bit. The blade needs some TLC and silver fittings were intended to be shiny. And that is well selected wood that would look beautiful with a bit os proper oiling. I don't think to would take much work to bring this piece up to its former glory.
