There is 1 original bassoon of the firm Willis & Goodlad in the Hichwa-Rachor database. The firm flourished in London from 1825 to 1834 and was founded by John Willis & John Dunkin Goodlad. John Wills was a renowned flute maker who played an important role in establishing the 8 keyed flute as the instrument of choice in early 19th Century London. John Goodlad was principally a business man and not an instrument maker.
