Close-up picture of the signalbox, which is to be seen on the left hand side in this picture of my Finsterwalde TT scale (1:120) diorama: flic.kr/p/Pk2Pqr
The building is a TT scale model Arnold (now a brand of Hornby) brought on the market in 2017. It's a resin model with a nice brick structure. Since the colour was too bright for a prototype located in the North-Eastern part of Germany, I had to repaint with the characteristical dark red brick colour.
