Hm ...
Kurowski sometimes used crude names for his stories, so I'm not 100% conviced in this case, but I will took over Totzek into my own list with the remark "according to Kurowski" ...
Do you have the one or two sentences before that kill claim for Totzek? What did Kurowski write about the circumstances?
As for Fw. Otto Arnold, I'm also not sure with that 10 kills on one day (11.4.1945).
Otto Arnold came over from H.Pz.Jg.Abt. 742 to s.Pz.Abt. 501 (Tiger) in July 1944 during "Bagration" and must have had some tank kills during the heavy fighting there too. He also served with s.Pz.Abt. 424 (ex 501) in January 1945 ...

I would like to trust the post from raoul hernandes as he claims to have spoken to some time witnesses and consulted some local archives, story seems to be correct and so Fw. Arnold did NOT have another 10 tank kills on 11.4.1945.
