Furatech makes the plugs on the end of the cable, one can buy the separately. In fact they are considered one of the better makers of these plugs. That pair of them are not at the high end of their line up.
No Clue if Furatech makes the cable part as well. Those look to be non-production made. (the shrink wrap looks home-made) Also no clue as to the actual wiring within them.
You can go read, and ponder for a long time about whether powercords can make any difference. I simplified things for myself : a badly made cord will harm your sound quality (and possibly your gear and your nervous system). A good cord will not. A great cord (independent of price) will make the sound quality more to your liking.
IMO, if your are looking to play with powercords (IE not use generic cords, and Markl rates some of them pretty well) and these cords are in your price range, and spark your interest due to the fancy plugs, and the fat cable, then go for them, and post some impressions vs. your other power cords for us to read. Many "secrets" show up here on the boards due to experimentation by the posters here.
Now to answer your actual question, no honest knowlege on those cables you are showing pictures of, sorry.
