All that can presently (June 2019) be gleaned from sheet music covers and by internet searching is that Bernard B. Brin has 6 works published between 1915 and 1924.
Of ragtime interest is
Jitney Bus Rag (1915) published by
Brin Music Co., Seattle, Washington, USA.
Surfers are welcome to contribute information about this composer.
Vince Giordano, bandleader of Vince Giordano's Nighthawks, sent me three titles of Brin's works on 23.12.2017. Many thanks Vince!
