Introduced in Persimmon in the 1964 Catalog. It was not shown in the 1965 Supplement but was in the 1966-67 catalog in Amber, Bluenique, Persimmon, Avocado, and Ruby. Viking dropped it when the 1967-68 catalog came out, but it was brought back by Dalzell Viking for a short period in the 90's in Crystal & Black.
