I have a !939 Leica 111B with F2 Summitar which I bought about 25 years ago from an old gentleman who was a medical officer during the war and ended his tour in Germany.I presume he liberated it, though no details were disclosed .It came with 2 boxes of Zeiss reloads and 2 100ft. bulk rolls of Agfa film.It still works though the small viewfinder and all the manual settings send me back to my Nikon Fm3a with the thought I must try again soon if only to keep it working.I must fish out the last negs and give them an airing in the darkroom. But as I remember my Nikon with its set of 30-40 year old lenses does perform a lot better with no effort required.
