While papers are nice and as a beginner myself I too look mostly at papered blades, the more important thing is that you like the blade itself. The Topic wether to buy papers or the blade has been discussed here a lot, so if you are interested in reading about that, there is a few posts😅.
For me personally they are just a level of security, since with my limited knowledge it is easy to make mistakes. Although, if I saw a blade I really really like without papers I would probably go for it.
Your Waki is an attractive blade and I´m sure you´ll have a good time studying it! The Koshirae adds to that as well, of course.
