TACHOMETER,SPEED , WOODMAN'S,PATENT,SEPT. 12 ,1876,OLD

 I found this in an old tools box of my Grandfathers,A Woodman's (Tachometer/speed indicator) Patent Sept. 12, 1876 around the center of the face of the tool.It is 3 11/16" x 2" x 3/8"and weights in at 2.3oz's.Super size the photos for larger and better images.It still turns and works and has very ornate cast feature to it.Besides the old patina ,there is an issue with the left side of the housing of the dial,look at images.Looks to be wore or a manufacturer's defect,a second?,if they had that back then?Just FYI .It's a very  cool item for sure,not many around.Buyer pays all shipping by zip or postal codes and insurance if requested.Thanks for looking and look at our store for other items of interest.
