    the pic with the numbers is just something i found with google.
    im still not sure if the bottom pic was just a hand tool or if that skinny end was also like a mount
    on some of the old speedo/odometer it also shows that little knob for resetting odometer?
    i am still trying to see if i can get this for few days to have better look
