Interesting comment about the extractor, which is a piece fitted to a slot under the bolt in the action body and is carried back and forth by the bolt. I do not recall how the lip on the extractor body actually gets ahead of the rim, but it has worked fine in thousands of 67s and other Winchesters in this family. The action cocks on closing. The safety is a cylindrical part with a tab for rotation. It rotates clockwise ( tab upright) blocking the firing pin. This is a very dependable safety mechanism. These rifles are plenty strong for the .22 cartridge. The bolt locks on the bolt handle. I would not hesitate to fire it as long as the bolt locks up properly and there is no obstruction in the barrel. I would likely fire the first round at arm's length rather than against my face. In this part of the woods, a nice 67 sells for $ 125 to $ 150. I would judge yours to be at the upper end or more, due to the Britishicon markings. However, if you decide to sell it, it is only worth what someone will pay.
