Now we have to find that non issued Krag in the cosmoline that has not been touched by human hands for the last 100 years.

My dad bought a 1917 Enfield in the 1940s and gave it to a friend that really liked it, then he bought another for himself. The second $6.50 rifle was new in the cosmoline, but he promptly sporterized it. Not as bad as it sounds, it was built from parts, Remington, Winchester, and others.
