SW EG-339 A New Mexico Windmill US-4070403 A Western Windmill

The first postcard shows a lonely windmill standing in the middle of New Mexico desert country furnishing water for thirsty livestock.

This is my second American windmill - see http://flynnfrogg.blogspot.com.au/2014/09/sw-dt-301-texan-windmill.html where there is more information on American-style windmills in general.
This postcard came from Maxine K. (10 November 2014) one of five postcards sent in a Swap-bot swap.

I have since received a third American windmill postcard.  This one is merely titled "A Western Windmill" and there is no indication of locality.  This postcard came from Amy (1 July 2016) Postcrossing.
