With regard to the Luftwaffe Loss records at the IWM, you need to always approach these with a certain amount of caution.

Let me give you a couple of examples:
1. Those records show Ebner & Zwick of 2./Erpr. Gr. 210 as being shot down in S9+DU on 27/9/40. The correct code was S9+DK, which information I received from Ken Wakefield initially decades ago from a document he copied to me.
2. Check out the spelling of the names of the crew show down on 5/10/40 in S9+GH, W. Nr. 3383 in the IWM microfilm records. You will not find the correct spelling of Duensing & Krappatsch.

So I would respectfully suggest that you do not dismiss information in books, as oftentimes that information is far more up-to-date and correct...

THAT is why I suggested you quote your sources for the specific information you request in threads on here. There are many on here who have accessed over the decades the records you mention, and garnered a hell of a lot more information from private sources to supplement those official records. If it's 'boring' for you to quote your sources, then you may find that that will result in less assistance than you may otherwise receive...

To reinforce what others have said, sometimes books are more reliable because authors have done more work, taking into account the limitations of the source material rather than taking things at face value. Wartime sources are invaluable, not infallible. The Luftwaffe was hopeless at spelling personal names and non-German place names, for a start. Take Ofw. Kuno Dollenmayer/Dollenmeyer/Dollenmaier — all spellings in primary sources, so how do you decide which is right? Or Oblt. Theodor Spies/Spiess of 5.(F)/123 … Or (from the IWM records) "Grumone" in Italy — on maps it's Cremona, so do you believe the German records?

Hi John, thank you for the information. As to spelling names, I always spell the names as they are written on the graves in stone. I guess there will be cases where this is wrong, but I hope the family may have corrected any miss-spelling of their sons. I'm sure I had the pleasure of meeting you once at the IMW while you were gathering information for your book "Zestörer". I will not be offended if you do not remember me :)
I should also add, I know I have only been on this site for less than one year, but I have been researching Luftwaffe Losses for 41 years, so I would like to think I know a little bit about this subject. I do appreciate all the help from everybody here, I find this site the best site to answer my many questions and to get the facts right. I never claim my facts are 100% correct or error free, I believe no one knows it all (Well, with the exception of Peter Cornwell, that's a compliment Peter!), but I am glad of the 'Experten' who know a lot more than me. Lets hope this allows you all to understand me better, and accept me into your ranks. Kind regards, Steve Roberts.

There has been a transcription error, so the code is shown as 59+DK, rather then S9+DK.
I have informed them.
