Tom I think you're right that we didn't discuss a problem of influences of Polish sabres on development of modern european sabres hilts on previous threads. Anyway here 
http://www.vikingsword.com/vb/showthread.php?t=108 at the bottom of a page is a diagram where you can clearer see how the development of sabres in Europe took place - more or less probably. But of course I don't mind if we dig it deeper just right here on this thread - more, I'll be even very happy  

 . 
Best regards
