A model 1918 Mauser is an anti-tank rifle, about 6 feet long. You are probably referring to a Mauser 1898 model made in 1918. In very good condition, probably worth about $300. The K98k is the more sought after model currently.
In life, strive to take the high road....It offers a better field of fire.
