This is one of the rarest Nikon lenses in F mount. I heard from one unofficial source that only less than 1,000 units have ever been made. This estimation seeems to agree with the serial numbers of the three examples known to me. The lens was released in June 1968 when it replaced the 135mm f4 short mount of the same optical construction in RF mount. It was again replaced by a newer 105mm f4 bellows lens in Jan 1970. This short production time explains why this lens is so rarely seen today. You won't see it in almost any Nikon reference books. Even the fabulous "Complete Nikon System" by Peter Braczko did not mention about this lens, although the book did include many other rare prototypes. The only accessory that comes with this bellows lens is a 43mm to 52mm step up ring. When this lens inherited the optical design of the RF 135mm short mount, it also inherited the 43mm filter thread. Although 43mm is common for RF lenses, it is a fairly odd size for the reflex. In one old ad, Nikon boosted "Actually, every Nikkor between 24mm and 200mm takes the same 52mm filters, with the exception of the 180 f2.8. That even includes the 80-200mm zoom". I guess this is the philosophy behind this step up ring. There is no dedicated lens hood known to exist.

The 43mm to 52mm step up ring is the standard accessory for this lens. There is no marking or any Nikon logo on it.
The RF 135mm f4 short mount was designed to be used with the rare Bellows Model I. It was released in Jan 1959, the same year the Nikon F system entered the market. A speical adapter called B-F tube (later called BR-1) was designed to allow this lens to be used on bellows made for the F system. The serial numbers range from 578000 to 580000. The first few hundreds lenses were marked as 13.5cm instead of 135mm. Its long mount successor in F mount removed the need for this BR-1 tube, although they both share the same optical design and preset aperture diaphram.
