Re: USRG-TP30 pricing, sanded to raw wood & tung oiled.
Difficult to put a ballpark price given the refinish, but I can tell you that I've owned two of the USRG30s, in very good to excellent and both sold for around $800-$850.
When did you sell? I did a few searches and seems like they've been selling for $1500+? The last one I could find on forum sold for $1800, can't post links.
