It depends on the way how the blade was stored, within the scabbard or not, dry or wet conditions, oiled or not. In most cases the front of the sword is most corroded.
The pattern is of importance for the corrosion if we have a rough grain with openings. If we have a fine grain without openings, the corrosion sensivity is much lower.
I think this beautiful sword is a Oriental contract work for a European customer. I know, that deeply curved Persian or Ottoman swords has been very popular in the armys of Napoleonic time. Proven officers often had been rewarded with mameluke sword types.
