Some swords I need opinions on, cant quiet identify...

Hi, i recently bought a large estate that had about 70 swords in it, and I have sorted through most of them, but these four are giving me some trouble on identification. I would appreciate any help on ID, country of origin, value, and so forth.
416 (see pics) is a soligen made short sword, very cool, just cant figure out what country it was made for, note printing on guard.
446 Likely a reproduction of something? maybe korean, does it have any value?
447 original tag calls it a Japanese field spear, 250 years old or so, appears authentic, but really could not find anything like it, seems almost african to me.
445 Interesting, very long sword, it all seems old including scabbard, but note if possible the inner lining of the scabbard, a woven, plaid cloth, I cant even get to the country on this one.
Thanks in advance for any comments!

I think I can help a little:

416 is Saxon Artillery Faschinemesser Model 1879.

The marking on the crossguard is for the Replacement Battery (Ersatz Batterie) of the 28th Field Artillery Regiment formed 1st November 1872.

There would originally have been a two digit date marking and a Royal Cypher/Crown - probably on the back of the blade near the hilt.

445 looks like it could be from the Sudan or a Tuareg sword from North Africa.

I thought 445 could be a Scottish sword from the highlands.

447 could be a Japanese yari(term for spear) but you are right most of them don't look like that. I have seen a few Japanese pole arms that look a little similar the pole was broken off. How old do you think they are?
