I have two custom rifles built on Interarm Mark X actions. Both are marked Interarms Mark X; Manchester, England; and CZ with the C inside the Z inside a circle. What actions do I have? Do they both come from Whitworths? Interestingly, they are finished inside and out as nicely as any commercial mauser action I've ever seen and are extremely smooth in operation. I'd love to know what I have. By the way, one action has a serial number A2894XX and the other B2961XX.
