Thanks Sally: Had to retake about 100 times lol I love this instrument. Not to hard to learn.
my book "The Story of the Hummel" was printed as the catalogue of the exhibition "Die Hummel" in the Museum Cloppenburg / Germany. More than 50 historical instruments were shown. Look at:
181 pages, colour photos, history of the instrument from medieval times to 20th century, 44 instruments in the appendix with all measurements. hardcover.
The price is 22,- + 7,- shipping (around 42 $ ) Shipping time could be 3 weeks because of proof at airports. 2 books had a shipping time of 6 weeks !!! (with a steamship?) Best is to pay with Paypal in (EURO) to my e-mail adress
