The design of this lens is similar to the 11228 version which was launched in 1968, but it carries different features, also without serial number. Firstly, the aperture is only from f/2.8 to f/8, instead of f/2 to f/16. Also, the rear structure of this lens is different from the official batch, which has two cam or three cam design. The lens comes with rear lens cap.
