Rusty saber. After a couple of days of cleaning with wd and a brass brush, a mark is visible, crescent moon
The wood is the same color everywhere, even in inaccessible places

Saber for identification.
 

Very beautiful and rare sword. Possibly Polish from the 17th century.

I agree.

The langets look a bit funny. The third photo show faint traces of sickle and grapes marks associated with Genoa. This style of sabre is more 16thC.

I wonder if the odd thinness of the langets might be result of corrosion and deterioration and material crumbled away. I agree as well this form is indeed late 16th century and of course extended into 17th, but looking at this more, it looks breathtakingly old!!

The sickle and grapes mark which was associated with Genoa (though used throughout North Italy, Genoa was the port of departure) was used in Styrian centers of blade making. According to Ostrowski, these Styrian centers were key sources for Hungarian blades and in degree Poland, though they also had Lvov.

We dont often (ever!) see a saber of this type around here! Thank you Aspalothos!

The blade appears to be from the end of the 16th century. The hilt however seems to be an imitation to me. Still a nice sword.
