I was browsing through the latest issue of the Historic Brass Society Journal yesterday and was happy to come across the below reference in “Correspondence” by Stanford professor Herbert W. Myers. The context of the citation was a discussion of trombone iconography (the way the instrument has been depicted visually in art work, etc.). Here’s the reference:

“I wish to acknowledge the website of the trombonist Will Kimball (www.kimballtrombone.com) as the source for the Garbieri, Spada, Collona, and Mitelli, and Kircher citations; these (and other) seventeenth-century illustrations of trombones can be viewed at https://www.kimballtrombone.com/trombone-timeline/17th-century/” (p. 232).

Thank you to Dr. Myers for his generous citation.
