You got me curious, so I went to vokey.com and did a search through the Wedgeworks archives (www.vokey.com/.../archive.aspx). I could not find anything that matched, so my suspicion is that this wedge is a) older than 2013 or b) a special edition or custom made. There was a hand ground 60V, but the details did not match. Nor did they match the hand ground 60-M. Not sure where else to look, other than hope that a Vokey aficionado may log on, see this, and be able to identify it.
