Added another Belgian military trombone image (Madou, 1832) to the 19th century timeline (1st half). It’s shown below, along with the other entries from the timeline related to Belgian military trombonists. There are 4 images total, all of them from the first half of the century and all showing rear-facing trombones. An interesting little slice of the history of the trombone.
