The Boy Scout fiction of the pre-WW II period is very inexpensive on eBay,

 

You can get a great many of these books for free on "archive.org".  They even have recorded readings of some book:

Much of this literature is before WWII and even WWI, and some was done with the Boy Scouts authorization.

Percy Keese Fitzhugh was commissioned by the BSA to produce the various series he penned.  His book "Along the Mohawk Trail" is a fantastic book for boys to read and are the basis for the characters in his series.  A lot of them are in re-print as well and I have picked up some of the books for <$5 so it's not all that expensive for some of the books.  They are an easy read and quite addictive even for adults.
