Wood doesn't last long outside, which is why most weathervanes that remain are metal. This one was made by hand, likely using a pattern from a hobbyist magazine. Traces of the original gray paint remain. Traces of the attached mount remain as well. One can tell if a wooden folk art weathervane is authentic by the age and wear...as there are prevailing winds (and an imperfect balance) the wear should be uneven. I have seen some nearly destroyed on one side, but with plenty of paint and color on the other.
