German Sauer Dish

I need help identifying a mark on the bottom of a German Sauer dish. I have had the dish approx. 30 years. Handed down from an old German friend of my Father's. It is in mint condition with a picture of a town Lauingen/Donau on it. The stickers are still intact. I have pictures I can send. The mark on the bottom looks like a clover with what looks like a pine tree in the middle and the word original above the tree. I can't make out the rest of the words under the tree but under the clover is 16B Any help??? please reply
I am interested in selling this item.
