Clock with Radium paint.
1940s Westclox Alarm clock - Model is called SPUR, luminous hands and Numbers. Works much like the Big Ben of the era - except SQUARE. The SPUR of this style design was made between 1938 and 1950. This one is likely late 1940's. Loud Ticker and Loud alarm too. This is the rare white (Ivory) model. Most of these are Black. Dial numbers and hands still glow well. ORIGINAL CONDITION - not a restoration. Movement Cleaned and oiled. 4-3/4 x 4-3/4 inch case. Dial is Mint. Loud ticker. Loud Alarm.
With my Inspector Alert, I measure, at the surface of the dials (α+β+γ) ≅ 274.90 μSv/h
