Zahl amassed exceptional riches and stamped his mark on the business life of Nordland for several decades.
When he died, the Kjerringøy business and its earning power had been declining for a couple of decades, as was true for most of the other northern Norwegian merchant posts.
Local merchant, farmer and politician Gerhard Kristiansen (1868-1937) took over the business and ran it from 1900 until his death in 1937.
The commercial operation of Kjerringøy trading post was discontinued at the end of the 1950s and the premises were bought by Nordland Museum in 1959.
