I worked at Frye Manufacturing from 1964-1966. I was an expediter and later a designer for spot and process carbon paper. I worked at the plant on Dean ave in Des Moines, IA. I knew of Mr Wissinger and the work he was doing in the research building just west of the production building. My under standing was that NCR was working on their own (N)o (C)arbon (R)equired product and had a significant head start over Frye.Poksnee (talk) 22:03, 12 July 2015 (UTC)
