Identification of a sword

[Iain]

This strikes me as an attempt to imitate a cinquedea of the 15th century, although not one of typical form.

However, I strongly suspect it is a 19th century "historismus" product. The blade may well be taken from an artillery pattern, the guard is certainly, at least in my opinion, not of any great age.

Reproductions were quite common during the 19th century and still hold value.
