According to J. Anthony Carter (book: German knife and sword makers) the oval logo was used on late naval daggers but I never seen original (naval) one. Just some fakes.

Personally I own nazified first model with the "early type logo" - stamped name on one side and "Z" on crowned shield on the other side, and I wouldn't go for an oval logo without other solid references. Doesn't mean I'm right, just that I won't get burned if this information isn't true.
