LD Haning is the Cadillac of Civil War accoutrement. While other makers closely match materials, LD Haning strives to come as close as possible to known examples found in battlefield museums and private collections. The end product is something that is probably as good as it gets in the hobby - and exact, indisputable copy of an original.
Be warned though - this is the top line, so expect to pay the price. But what you get is a fine product that carries with it the research and effort to make it stand above the rest.
