See our Model 66 extractor compatibility notes: older style (66, 66-1, 66-2, 66-3) vs. newer style (66-4 and later) extractors are not interchangeable.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eFunction\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eThe cylinder and yoke assembly is the rotating chamber unit that holds and aligns cartridges with the barrel for firing. The yoke (crane) allows the cylinder to swing out of the frame for loading and unloading.
