Remember it's a 1942 Bren, manufactured in the middle of a major world war and the finish, when new, is not likely to be what you'd get with a gun made in peace time. Be careful about refinishing the wood and metal parts to a finish better than it left the factory when new because it's all too easy to end up with what some may call a civy refurb but I prefer to describe as it having been "tarted up".
