Most recently used as a seal tannery, the building was built by S.W. Mifflin Ltd., a highly successful salt fish processing and export company in Catalina. Started in the late 1930s, S. W. Mifflin Ltd. grew to occupy nine buildings and operate five vessels within 10 years. The ships collected fish from Labrador and around Newfoundland, and brought it to Catalina to be processed, salted and dried before export to Italy, Portugal, Spain and the West Indies. Mifflin closed the plant in 1989, shortly before the collapse of the cod fishery in 1992. The Barry Group Inc. bought the building and it operated as a seal tannery for almost twenty years before closing in March 2012.
