I found an 1899 Smith & Wesson with a bone next to it. Because of time, I will post pics of the gun later. Can anyone tell me if this is a human tibia? I just need to know if this bone is human! Both were found in a ravine between 2 train stations. Can anyone tell me if the markings are animal gnaw marks, or initials carved into the bone? BTW, the gun has 9 notches carved into the grip. Thanks so much!!
