Hi,
I sincerely appreciate your ambition to share these internet auction photos with us. It would be even better to have the auction link posted instead of only the photo link for convenience of checking if the site contains some additional information. It does for example happen there is a scan of the reverse side of the photo with interesting information, or info from the seller, helping in identifying the photo.
Sometimes the auction also contains other photos worth following up - not only Luftwaffe but also Wehrmacht, Kriegsmarine etc.
Cheers
Goran
