National 9 1/2" Small Base Spiral Cone Excellent

We’re assuming that all you National nuts out there will know exactly what this 9-12” special National spiral cone is for; seems to us that it would be for a National tenor guitar, or mandolin. Has the smaller base at its apex, for the smaller biscuit. Also has that cool spiral for all that hot music, and to make your music even hotter has the official National “shield” impressed right onto it. Just found here, uncovered from years of storage; unused and perfect. $75
