Kr+ punze identification golf brooch

[Eleonora]

Dear Fellows,
I have a brooch with Kr+ mark.
I have found Gustav Kropp, but his mark contains Kr only.
Here we have + mark and frame additionaly.
Is this Gustav Kropp mark, anyway?
Lenght 58 mm, weight 3,22 gr.

For all who wants to know who is the maker by "Kr+" mark in rectangle frame.
This is GOLD KRAEMER, established in 1941 by PAUL RUDOLF KRAEMER, in Cologne, Germany.
This particular information you can find directly in this forum, posted in 2017.
Could not find it before, but maybe I have insert a different phrase to the search firld, before.
To the administrator: would be much easier, if you could add this mark to the catalog of indentified maker's marks, which is linked above forum conversation area.
You can use my picture, which is quite clear and sharp enough, I suppose
