This is a very nice original Fhinney-Walker dash clock with Patent dates from Feb 1902-Oct 1915. The face and bezel measure right around 2 1/2" in diameter. The time is set by moving the bezel out and turning it, and I believe it is wound by pushing in and turning the bezel as well. Works but will probably need a good cleaning. Has been sitting in my showcase for several years. $200 plus shipping.
