Yes, you're right about the distance between the dedication and the Eickhorn logo, usually it's about 20 mm (+/- 1mm), here it looks like 23 mm at least. However, if the differences occur, then it means the logo and the dedication were done with 2 separate templates and not with one integral template, thus even 2 or 3 mm differences can be acceptable.
I compared it with Full Röhm Eickhorn I own and I can see some differences in letters' thicknes here and there, but they might be linked with some aspects of the etching process. Hands on inspection would bring more light, but it remains impossible so far.
BTW. seeing the obverse of the blade would be interesting as well.
