I agree with Diane regarding the concertina.It was lightweight portable and cheap compared with brass instruments in the mid 1850s. It was taken up by The Salvation Army and Concertina Bands became very popular playing a yearly competition at Bell Vue Manchester and Crystal Palace. it's popularity continued to The Music Halls,it became a popular instrument to take to sea,but I doubt if the salt water did the reeds any good. The Concertina is regaining it's early popularity and Workshops are pulling in large crowds.
My vote as always the Concertina.
