Not much to find on the internet. It could be the Baseball Cap by Jeremy Shafer published in BARF spring/summer 2006, but I wasn't able to track down a picture. Maybe you can contact Jeremy and ask whether it is his model.
Apart from that I really disapprove of the page you found this picture at. It only uses stolen pictures without giving any credit to the authors of those models. Neither asked the person who made the page for permission to use those photos (I know because I asked one of the authors who originally posted several of the pictures).
I contacted jemery...lets see if he will reply me or not.
Regarding that particular website...I have no idea. I am not the admin there...just found that picture there.
You could try to replicate it, assuming that the reason you want to know who the author is to fold it. I Believe it looks very simple, just good shaping.
that would be nice...that would than be my very first CP origami...as I never fold by CP before. that might be a good exercise for me to learn on how to fold with CP.....on step moving forward to fold the ryu zin 3.5
