Risszeichnung technical cutaway on warm cream paper: a load-bearing inference switchboard built as two adjacent cartridges. The left cartridge carries a large applause dial; its single hot-pink organic valve is swollen and disconnected. The right cartridge is smaller, with green structural rails and dozens of copper scheduled-pipeline tubes passing through it. The right side carries the building. A real hexagonal honeycomb lattice forms the modular frame. Clean single-weight Teenage Engineering and Braun-Rams linework, vast unoccupied ground, three numbered German callouts: 01 BEIFALLZÄHLER, 03 TAKTPULS, 06 DAUERLAST. Lower-right German seven-item parts list includes 07 UNBEKANNTE ABSICHT. One small green Bureau seal struck once, registration crosses at corners, thin pointer lines, analogue-warm trace of patina.
