Hello, Peter...
Thanks for the information. I am acquainted with the
www.luftarchiv.de site, although I have discovered new areas within the site that I never knew were there... !
Sadly, the reasoning for the unusual coding I am enquiring about seems not to be covered, and will have to remain a mystery for the time being. A lot of the other information was already know to me, but it is extremely well presented for others who are perhaps not as conversant. Definitely a website to be recommended, although curious minds should ideally have a better knowledge of the German language than myself, given that the bulk of the information is in German, with only the menus having an option of English.
I was, however, very interested to see an apparent link to
www.stammkennzeichen.de, an archive of the four-character alphabetic codings, but sadly was unable to access this. Would you know if it is available, or is it
work in hand...?
Thanks again for taking the time to reply... much appreciated...
Regards...
