I was watching the "How Do They Do It" on the Science Channel last night. Colt it remaking the 1862 Revolver again from back in 1862. They are using the same exact parts from 150 years ago. The only difference is today they aren't hand made. They have a machine that can make all 52 pieces in 12 minutes then they have a guy that can assemble the entire gun in 10 minutes.
