vintage knife carving set knives, yellow catalin bakelite or plastic handles

1950s vintage carving and serving knives in beautiful red marbled storage case. The handles are a swirled plastic or catalin, yellow and white. The blades I think are stainless steel, marked from the Farmer's Co-Op Elevator Company of Fullerton North Dakota. The entire set is in very nice condition, I don't think it was ever used at all.
