Comparing the project sword style at #1 what we appear to be looking at is the same design as shown on
http://www.vikingsword.com/vb/showthread.php?t=314 See # 11 picture number 12..Scroll down 12 pictures(final picture) and see 3rd from right sword.
This Museum exhibit is in Istanbul so is likely to be "Mamluke" linked which places rather a more important hand on this style. Definitely more research needed on this !!
