This upright piano was bought in Uitenhage, South Africa at a store named H.F. Couldridge Ltd. in +- 1955. According to the shop owner the piano was 25-50 years old.
It is a black upright piano and we think the keys are made of dark wood and ivory but we are not sure.
Can anybody tell us more about this piano and its history? I managed to find a lot about Alex Steinbach (Korea), but not C. Steinbach (Berlin).
I have no record of a C. Steinbach or J. Steinbach.
