In 1926 the Heckel company presented its products at the craft and trade show at Biebrich Palace. Here, the company presented a selection of 40 antique Heckel instruments, as well as a variety of other Heckel products. Among the exhibited instruments were not only bassoons, contrabassoons and various heckelphones, but also oboes, clarinets, flutes and much more.
In addition, the individual production stages of a Heckel instrument, from the wood selected to the fin- ished product, were presented with the help of vivid woodcuts, drawings and diagrams.
