Roycroft Squat Vase

I have read this referred to as the “nuclear power plant vase” or “gourd vase” but I prefer squat vase. This has what is known as the second mark and dates it somewhere between 1906 and 1916. The patina is untouched original and in nice condition. Measures 4 1/8th inches tall and 6 5/8 inches in diameter.
