I have 2 Enfield rifles. One is a US property Savage and the other is an Austrailian Lithgow. Both are in about equal condition. The Savage has a bluish canvass sling and the Lithgow has an original leather sling. I think they are original but the Lithgow is a 1941 marked receiver with a 1942 marked stock. I can only keep one . Which one is the more desirable or valuable to have? Thanks
