Made in Japan at the Nagoya Music Factory along with the Conqueror and Kingston mandolins, the Bruno was reportedly marketed by Teisco, the Japanese company famous for its gimmicky guitars. Hope the Bruno company (which made acoustics in the late 1800s and early 1900s) didn't mind.
The instrument below is a Bruno "Royal Artist," which appears to have a different bridge than the one pictured above. I'm told the Royal Artist is a mandola, but it may just be a long-scale mandolin, which is the case with many of these instruments. I don't know why, but it seems to be de rigueur to photograph a Bruno in its case. I have plenty of photos of Conquerors and Kingstons out of their cases, but not Brunos. Why is that?
