Magdeburg 1933, that means Bann 26, Gebiet Mitteland, Obergebiet Mitte. Unfortunatelly I dont know whay they used that knight but I am sure it is related to the city.
And, to finish, the Tinnie on the right:
Stendal 27. May 1934 - Bann 27 (Altmark), Gebiet Mittelland, Obergebiet Mitte

PS: It is better to look for info over Tinnies when drinking a glass of “fast frozen” Havana Club Añejo Reserva (If you have a small bottle, leave it on the freezer and drink a glass in case of emergency or bad day at work).
