Queen Isabel the first sword

The sword is 31 inches long. it has a small chain rapped tightly around the handle for the grip. The "T" handle has the name of Isabel I, and Fernando V on one side and Donto Monta and Monta Donto on the reverse side. It has alittle damage about 6-8 inchs on the blade tip, pits do to water and rust. There's numbers and letters on the blade next to the "T" handle that is hard to make out do to battle scars as another sword had struck it. Its in good condition for the age of it. I also found out that Queen Isabel is also family to Henry III, and Henry II. Henry II is her Great great great Grandfather and Henry III is her great great grandfather.
