Good posting.
This is a great original "teaching" document from very early in the DB 605 development, dated 10.41. It does show the very close relationship between the DB 601E/F and the DB 605A/B/C. However, some detail points about the 605 were changed before production. Additionally, the DB 605 D/E/F that is covered here was never put into production. The DB 605 D was a very different engine by the time that it was produced in 1944.
