Oberzahlmeister of II./J.G. 52, Erich Hartmann
 

Does anyone know the name of the Oberzahlmeister (Paymaster) of the II./J.G. 52 in November 1944? His surname appears twice in Erich Hartmann's Soldbuch (Pay Book and Personal ID) that was issued to Hartmann on November 1944. I am pretty good at reading Sütterlin, but when it comes to bad or stylistic handwriting, I'm lost. It looks like the last four letters of the Oberzahlmeister's last name are "gang".
