Trying to validate Factory code of TN+AG for a He111 shot down on May 10, 1940

[Larry Hickey]

Hello,

After a great deal of piecing together photo and other evidence, the EoE working group has identified an He111 of 7./KG53 that force-landed and burned near Ell, W of Redange, Luxembourg, on 10 May 1940, as carrying the a/c code ?N+AG. The first letter could be a "T", giving us "TN+AG." This apparently is a factory code, and not the A1+?R you would expect from this unit. Probably a new a/c just going into service with 7./KG53, and there not being time change to a unit code before it was shot down on the opening day of the Blitzkrieg. I know that there are experts working on these factory codes. Does TN+AG work for an He111H coming off the assembly line about April or early May of 1940? Is it even a valid He111 factory code? If not a "T", is there any other factory code first letter suggested for that time frame? Finally, if the number fits, what would the corresponding W.Nr. for this a/c be?

Regards,
