Leitz nice tele lens Leica 400/5 400mm F:5 Telyt attached hood with rare rigid case, exc++++ c.1960

This is a tele lens Leitz, made in Germany, suitable for use with the Leica Visoflex system, the Leitz code is TLCOO (or 11766) . It's a 400mm F: 5 Telyt with attached lens hood, serial number 1746819 (c. 1960) , with M39 mount (but it cannot be used directly on Leica screw mount cameras) . It must be used in combination with the Visoflex I or with the Visoflex II or III (with these two it's necessary to use the OUBIO ring) . A is possible to see from the pictures it's in very nice condition, it's hard to find so beautiful. Focusing is smooth and regular, the diaphragms works well and the blades are oil free. Also the glasses are in very good condition, with some little dust inside and few very light cleaning marks (impossible to take pictures of them) . It comes with caps a double cable release and two Leitz filters, UVa and Yellow. All contained in a very beautiful and rare original Leitz rigid case. It's in great condition (please remember its age and its delicacy) , only one internal compartment has "rough" stains, I don't know what caused. I've seen several "cheap" case which contained a Telyt kit, but rarely I've seen these. A nice kit, not easy to find and not it's hard to find this lens in so beautiful condition and with this beautiful rigid case (I think suitable for Leica M cameras) . A great item for the Leica collector.
