I've listed another round of my duplicate Luftwaffe books on eBay. All are in "Like New" or "Very Good" condition, and they all start at $1. A pretty wide variety, so it's likely there'll be something to tickle your fancy.
Please see the attached photos for the titles, and check the listings at:

Thanks and regards,
