OK, this is not hi-res, but I combed through the season and got a ton of screencaps. Should've started from the ends (beginning and end), though. Would've saved a ton of superfluous work.
I got some other screencaps of the whole sword, with and without scabbard, if you want those too.
This is really a strange coincidence! I got suddenly interested in Much's shield over the past few days, but I just happened to see your thread on the front page.
The reason for the third photo is because there is a very subtle marking on the top part of the hilt (I don't know the names of the parts of swords, but I think you get what I mean). Sorry that these are kind of blurry!
