Hello,
the question is the size, you are looking for. Betwen 1/72 (Italeri) and 1/220 Z-gauge (zierlich), there is a real wide field.
The german revolution 1919 was driven by the poor city people and the soldiers (not the officers) of army and navy.
If you would look out for brickbuilded houses, you can`t get wrong.
Yours, Sebastian
