http://www.byrdaviationbooks.com/Byrd Aviation Books specializes in WWI aviation books and has an esoteric inventory of new and OOP books and collectibles. I don't know if the discount will offset the higher shipping costs to addresses outside of the USA enough to make the sale attractive, but it may be worth a look. I have done business with the Byrds for at least 20 years and I have always found their service to be among the best.
