The bow string is "tsuru" if you decide to rename the material.

They were scanned in at 300dpi, so the zip is about 8MB.

One of the problems, as with all Japanese war related stuff, is that its long history means lots of changes.  Heian stuff tends to be much different than Kamakura than Edo period (and so on).  Even when studying katana, it is amazing how many changes from the earliest to the last incarnations (the later being heavily influenced by European designs).  Luckily, the quintessential Samurai sword had a rather static form (despite the variety) from after Kamakura to the late Edo periods.  Yumi seem to be this way as well - having retained their assymetrical, composite form for centuries.  The quivers, on the other hand, appear to have change significantly from period to period.

C makes it easy to shoot yourself in the foot. C++ makes it harder, but when you do, you blow your whole leg off.
