Doing some homework I found a minor treasure trove of pulp magazine fiction, much of it available for free!
Following a link from ThePulp.net
, I found Age of Aces
a press that publishes reprints of aviation titles from pulp magazines. These are available as modern, trade paperback anthologies on Amazon
of fiction originally published in the 1930' - 40's.
If however you want to get a taste for them before you buy, they have selected stories available for free as pdf downloads on their Age of Aces Presents
page. I have no idea how many there are but there are fifteen on their latest downloads page alone! You can access them by links from the book pages or by following the web of links in the right-hand bar.
In addition they have a free gallery of interior
art from the magazines and biographies of the artists
I found this a fantastic window on what a pulp magazine might have contained and looked like in 1937. A great resource!
