I have for sale a Winchester model 1910 self loading semi auto rifle manufactured in 1912. The rifle is chambered in 401 cal. It is missing this clip, but they are still available online. The action functions correctly, but I have not fired this rifle but would not hesitate in doing so. The rifling appears to be decent, but the bore is a little dark, which can be expected from 112 year-old firearm. There is a minor bumps and bruising on the wood but all in all this is a very nice example of this firearm.
