Currently his vendor table is exactly the same as the npc across from him,
Joana Jinklebelly (selling arrow materials). I believe this to be a mistake as this is the only place in rivervale related to fletching; yet I can't purchase the materials required to craft my nooby bow :(

Fixed, pending update.
