Added this image and caption to the Trombone History Timeline (17th century, 2nd half). Interesting extra bit of tubing; sometimes you just do what’s necessary to make it work!

c. 1700—Passau, Germany: A putto decorating the interior of St. Michael’s church holds the trombone in an improbably way, necessitating an unusual extra bend of tubing at the leadpipe (see below image; public domain).
