If I may why are you restoring this particular arisaka? For me anyway a rule of thumb that I learned from many collectors is unless a sporterized rifle is a rare model like a real sniper or has sentimental value like it was your grandfather's/uncle's/dad's war trophy then cost wise it isn't worth it. A series 6 Nagoya isn't particularly rare or uncommon and you can get an unmessed with one for the amount you're sinking into this one.
