3C collet indexer fixture. (I\'ve been informed by someone more knowledgeablethan I that 1A and 3C collets might be interchangeable. According to a thread on Practical Machinist...\"According to one of the Machinery Handbooks, information provided by Hardinge, the only difference is the length. The 1A is 1/8\" shorter than a 3C and that\'s it!\") No manufacturer markings. Needs locking pin. Comes with 3/8\" 3C collet. Please refer to photos, as I\'ve not used it. No international purchasers, unfortunately.
