Probably in use since 1987
Blazon: Azure two staves topped with bunches of oak leaves palewise in fess argent
I wish I could have found something about these arms, because the charges are fascinating. I don’t think I’ve seen anything quite like them before. There is apparently a very impressive oak forest in the region, but I can’t tell whether that has anything to do with these unique charges, since they are specifically not trees. It apparently shared the name “Jettenburg” with a nearby bridge and/or corduroy road until 1558.
