I think the 190.Division forming part of Division Hamburg is a typo, it was 180.ID. I have been working on divisional OBs since 1976, unfornuately I never kept track of all sources. Of course Tessin and most major OB sources are countered. Microfilm records, magazine articles, 100s of books, and annuals I have not recorded. Presently, I have 5 thick volumes of typed divisional histories and OBs. Of course, research is on going adventure for me. Once, you get to lesser known divisions, I have discovered that typos very much exist!
