Erich,

Yes, the previous owner and a highly respected German collector (Albert) already posted an inquiry on this Forum. The link is Deutsches Afrika-Korps :: View topic - Suche Infos zu RKT Major Heinrich Hauptmann. Unfortunately, no new information has come of it thus far.

Here is a link to the AHF thread that has several photos of this amazing Afrikakorps RKT grouping: Axis History Forum :: Afrikakorps RKT Heinrich Hauptmann

Do you know anyone that might have some photos of DAK RKT Heinrich Hauptmann? He's not specifically identified in any DAK reference books so I'm now hoping someone might have photos or other information in their collection....

Again, any assistance to help research this DAK Panzergrenadier officer would be greatly appreciated :-)

All the best!
David
