Phill, Bob.
I'm glad you like the pictures!
All this material was purchased new pay per kilogram of scrap and delivering seed wheat and beef. Europe needed food and had plenty of war material.
Our Archivo General de la Nacion is in the process of digitalizing much photographic material, but does not have a web site to search and download.
I personally get this material, looking for it in this archive, when I have more interesting stuff I share with you !
