The sword is Oakeshott of Type XVa, but can also be placed in XVIIIa.
The mark of the workshop Missaglia, a m below a splitted cross is used upto 1452.
it has most similarties with the personal mark of Petrajolo Da Missaglia (late 14th century), but despite some references in the literature, there are no (authentic) swords of the workshop Missaglia known!
The pommel of type T3 is of similar type as the pommel of the famous sword of Estorre Visconti. (lord of Milan from 1412 to 1413) (cf. Boccia and Coelho no 85, Oakeshott XV.13 ROMs)
A blade with ricasso on a type XVa or VXIIIa would be very rare however possible at the beginning of the 15th century.
If the sword is authentic, it is made in the first half of the 15th century.
I personally would seriously consider that it is is a later reproduction, probably from the 19th century.
hope it helps.
