The police of the city of Leipzig had a very similar helmet plate (the lyra does not fit) but the coat of arms (as of Dresden) would be inverted. Is the image perhaps mirrorred?
Those are two very different Wappens. The one posted initailly has what looks like a Glockelspiel on the top, yours has a Fleur De Li. Plus, oak leaves are completely different etc etc. I think Mike nailed it, yours James could be Dresden. Maaaaybe?
