ACOUSTIC BELLOWS AFTER BERTRAM, WITH 7 DEMONSTRATION PIPES
19-012. Probably English, early 1st quarter 20th century, unsigned. Made of maple and pine, 23" long x 13" wide x 27 1/2" tall overall, with hand-powered bellows, 5-valve pipe rack, and 7 demonstration pipes of various sizes and shapes. This unusual acoustic demonstration apparatus is in very good working condition - 3 of the pipes work very well and 4 work but need more air than the bellows can now provide.
