German SilverPlate Spoon?

This spoon is marked 90 and then has a another mark. Would someone recognize the maker on this? Thanks so much!

 

Look at the link attached and scroll to Clarfeld and Springmayer. https://www.925-1000.com/Fgerman_marks_a1884_2.html

They used a mark like yours on both solid silver and silverplate items.

 

Thanks! I think that is the maker.
