One problem plagued this study from its inception: The authors could not examine all<br />
of the instruments personally and therefore had to rely on secondary sources in some<br />
instances. However, great caution was taken to use only the most reliable published material.<br />
Also, many colleagues, private collectors, and employees of the institutions listed in Table<br />
1 were very helpful in filling in gaps. An important question, not always to be answered<br />
through recourse to photos in catalogues, is whether the reversed valve sequence is fixed or<br />
interchangeable. Sometimes this question remained open even when instruments were<br />
examined personally, since their condition did not allow removal of the slides. Our approach<br />
to this problem will be discussed in detail below.<br />
Two further considerations might obscure the frequency of this valve configuration<br />
and the material presented here:<br />
1. Some instruments were altered so as to conform to the modern valve sequence in the<br />
course of repairs. 2
