We have a metal and a wood piece.  Both appear to be completely original.  The wood piece measures at about .103 while the metal comes in at around .107 (pending).  I am using a Babbitt tip wand so it is possible that these measure a bit bigger using a different method.
Both facings and tips are in very good condition, wood piece had a tooth gouge in the bite that I filled flush and then applied a patch over.  Both are rare pieces.  These are from an old estate and very likely they came from the 1980’s-1990’s.  The wood model was popularized by Joe Lovano I think, and the metal, Bob Berg.  This appears to be the much sought after solid silver handmade model.

Both of these pieces play excellently with power, depth, complexity and edge.
