Actually, Nichol Kola was bottled throughout most places in the United States and even in Venezuela. I have Nichol Kola bottles from California, Washington, Utah, Ohio, Iowa, Minnesota, Wisconsin, Florida, Georgia, New York, Arkansas, South Carolina, Pennsylvania, and Maryland.
By the way, I have a Nichol Kola bottle that is stamped either '62 or '63 on the bottom. So, I would say that Nichol Kola finally went out of business in the early 60's.
Keep looking for them on eBay.
