Vintage Phinney Walker 8 day car clock

PLEASE NOTE I WILL NOT BE SHIPPING BETWEEN DECEMBER 11 AND JANUARY 2 This clock I believe is from the 1920s. It was my grandfathers clock for his model T. I don't know whether the clock came with the car, I think it did. After what I presume is a century or almost a century of sitting in a box wrapped in paper in the attic-it was passed on to me. ...which honestly is a waste.
If there is someone out there with a model T, this might be for you.
All I know is that the it is really well preserved. The face is clean (see the photo) The brass ( well I think it is brass, but It may not be) is not scratched and looks incredible.
Have no idea how it works-it seems to spin. When I spin it to the right it changes arm positions and when I turned it the left the second hand seemed to start clicking. But I would highly recommend that the buyer take it to a watch specialist. I literally just took out of the box and really don't want to mess with it.
So it is a rare clock in nearly pristine vintage condition.
