A beautiful and well-crafted small portable radio, very "solid" — if you remove the detachable handle, it's a coat pocket radio, though a bit large. The MW tuning scale is calibrated in meters/10 (200 - 550 meters) rather than kHz, and the tuning is very smooth. The triangular tuning window is kind of unique both in its shape and in having all those cool European city/station markings on it!
