Found this at a gunshow last weekend. BSA, 1911,ShtLE, #1 MkIII. Matching numbers on bolt, receiver, barrel and nose cap. Had rear sight removed ,one piece handguard and volley sights. Metal had thin sticky brown film like thinned cosmoline. Used soft rag and oil to clean revealing deep blue finish. Furniture has smooth glossy finish, cleaned up really nice. Couple of people have stated probably target rifle. Here's some pics.
