It's strongly discouraged (verboten, even) to solicit values on this forum. Reason being; this site would quickly degrade into an arena for valuations and appraisals rather than friendly exchanges and discussions about use, maintenance and history. What you have there though certainly is desirable to some folks on here and you could politely ask for 'expressions of interest' from those parties. By the way where are you located, how did you come across this NOS (New Old Stock) head and what do you know about these styles of axes?
