Anemometer

Spotted this rather lovely mechanical anemometer in France recently, it looks to be nickel plated and the mechanism was simply superb.

Apparently Jules Richard 1848-1930 was a meteorological and aviation instrument maker in Paris, this type of instrument appear to date from around 1900, and there's suggestion that the Wright brother's used one in preparation of their famous fist powered flight at Kitty Hawk.

It seems like variations on the model were made into the 1970's but there was no indication of the date on this example.
