This funnel comes from a black-and-white photograph of Kramfors, built in 1892 for Kramfors A/B and transferred to Kramfors Rederi A/B in 1914. Rosanoski presumes the same livery applied to both companies.
The Kramfors parent, inherited by SCA, disposed of other shipping activities, retaining only towing vessels and what the source calls pråmar, tentatively translated as barges, from the 1930s until the 1950s withdrawal. Kramfors A/B merged into Kramfors Rederi A/B on 31 December 1952.
