Since fernando bumped the thread and I have not posted for a very long time I'd like to chime in with something new. Although this thread is primarily on Polish weapons I do think you wont mind if I share some stuff from KOH with you. Almost a year ago I bought a splendid book by Tibor Kovács on the topic of Hungarian hussar weaponry: Huszárfegyverek a 15-17. században (Martin Opitz Kiadó, 2010).
Although written in Magyar I still highly recommend it since it covers a lot of previously unexplored areas including early sabers from 15th century. It appears that (at least within the sector of east-central Europe)the period was full of great experimentation. Besides the "classic" Turco-mongol designs one can encounter saber blades mounted on messer and schiavonesca style hilts.
Late 14th century sabre:
Messer hilts with sabre blades (mid/second half of the 15th c.) :
Schiavonesca hilts with sabre blades (mid/second half of the 15th c.) :
The only example of late XV/early XVI. Hungarian sabre I know of - so called "Gothic saber" with an acorn shaped pommel :
Duo of mid XVI c. sabres:
All of the above comes from Kovács' book. Of course there is much more in it including all the other offensive weapons as well as harness of hun. hussars. Interestingly enough I have spotted a similar depiction of a "Gothic" sabre on one of our altars back here in Bardejov, Slovakia (former KOH, IIRC early XVI. c). Note the acorn shaped pommel and a wrist loop(?):
