A very good condition ( optics ) Leica summicron 50 2 Rigid ver 2 . Comestics little bit dents on the front but not serious n obvious especially put on filter and . SN 1895679 fell correctly on the range of 1894801-1896000 . Rigid is a must for Leica collector like me Len only include front Leica cap.
