I'm looking for someone with greater knowledge and resources in historic German heraldry than I've been able to do (they do NOT necessarily need to be a German citizen). I'm finding it very difficult and elusive to track down a historic coat of arms for the district of Berlin called Moabit, which, since 1920, has been a subdivision of the Mitte Borough. Oddly, I've found historic coats of arms for almost all the other boroughs, districts, and pre-urban-sprawl towns and villages, both modern and historical. Does anyone here have a .png, .gif, .jpeg, or .bmp image of such a coat of arms they could kindly upload for a private project? I would be very grateful, and at this point would even take low-quality scans. Thanks in advance!
