Charles Bruno immigrated from Germany and established his company in 1834. C. Bruno and Son manufactured and imported a huge variety of instruments in New York, continuing well into the 20th Century.
They made many models of guitars and banjos. An archived example of his illustrated catalogue circa 1890 shows a fretless banjo: the No. C featuring brass 8″ diameter rim, only 4 brass Shield brackets, Sheepskin head at an incredible price of $1.90 !
