I am not a expert, but if it is marked Germany, it is most likely post war.

I have no idea which war you are meaning, Ed. Possibly WW II ?
Anyway I doubt that the country of origin's marking 'GERMANY' is a realistic option to date a knife.
Listed as a post war mark for Gebr. Noelle GmbH.
Arrows are showing up in German trade mark directories in many different positions and combinations, such as the following couply by Gebr. Noelle:
Both of these are different to the illustration of this thread.
I would be pleased to complete my files with the additional Noelle Broths.' trademark that you are referring to, Vern,and possible registration number and date.
The location's marking 'SOLINGEN' below the illustrated trademark does convince me, that Gebr. Noelle was not the manufacturer of this post's knife. This cutler of table ware was located in Luedenscheid, c. 100 miles away from Solingen.
I regret that in my files I could not yet track a German cutler's matching trademark showing a circle with two arrows so far.
