Ardalt saucer

In addition to orphan photos, I love orphan china ... saucers, plates, etc. that are individual pieces of a long-lost collection. I've had this a long time, picked up at a yard sale somene where just because I thought it was so pretty. It is about 3" in diameter, and has a small insignia of some sort of creature holding a shield with a T on it and 1794 underneath. "Konigl.nr.Tettau" ARDALT No.7018 Germany...US...????. Tried googling a little on my own, seems possibly to be Bavarian china but couldn't find anything exactly like it. Would love to hear if anyone has any clues to tell me more about it!
