Centennial Carbon Fiber Tripod 4-Series and Highline Ball Head, both made by Colorado Tripod Company, and Benro Carbon Fiber Extension. Used once. Gorgeous and just about impossible to obtain. This could be the only 4-Series for sale anywhere. Go ahead, check eBay. (You'll find this tripod for a little more money and that's all.) You can't even buy one from the company. They have been on back-order for years. The same goes for the ball head. (Gitzo, Really Right Stuff (RRS), Leofoto, Feisol, Sirui, FLM, Manfrotto, Bogen, Leica, Hasselblad, Canon, Sony)
