My dear, I thank you for your time
Unless the question was not solved, I appreciate very much your Engagement.

Hope the expert of the region take a look at.
Cheers

I have looked for three days and have not found this mark in association with the Goebel company !! The known marks that can be found on the internet are quite different !! From what I can find the earliest mark was the triangle and half moon mark,, Then the crown and WG mark !! There are several things about your mark that are different from the known marks !! The width of the W is not the same,,the crown is different,,and as far as I can find,, Goebel never used a cross at the top of the crown !!
Now I am not familiar enough with the marks used before 1935 to even guess if this is a look-a-like mark or if it is one that has not been documented !! There have been instances of unknown marks showing up !! One of the members here is an expert on the porcelains of that region !! Perhaps he will take a look in the next few days and give his opinion !!

What is your location ?? Where did your Grandmother get this figurine ??
