The reason there are "knock-offs" is because in the late 1980's Billy Cook sold the company and his patents to Long Horn Saddle Company with a non-compete clause, meaning he couldn't make saddles under the name Billy Cook for a certain number of years. Billy Cook was originally in Greenville, Texas, so saddles made before he sold the company will say Greenville, TX, and they are genuine. Billy Cook saddles that were made after he sold the company that say Greenville, TX are made by Long Horn Saddle Company. After the non-compete clause was up, Billy Cook reopened his saddle shop in Sulphur, Ok. So the Billy Cook saddles that were made before he sold the company that say they're made in Greenville, TX, and the ones that say Sulphur, OK, are genuine.
Does that make any sense? Lol
