Ole Paulsen “Oslo weigh master?”

Our family history says Ole Paulsen was a “weigh master” for the city of Oslo. He died at age 45 on 15 July 1863. His burial is recorded at the Trefoldighet Parish on 21 July 1863. Cause of death was listed as “nervefeber” (typhoid). Are there any suggestions on where to find information to confirm his being a “weigh master” for the city? The death record appears to contain the word “arbeider” (laborer). http://www.arkivverket.no/URN:NBN:no-a1450-kb20060901020329.jpg Ole married Martha JANSEN (b.1821), they had three children John (b.1852) Fanny (b 1857) and Carl Martin (b.1860P) all born in Olso and recorded at the Oslo Domkirke
