There were no AI conversion kits for these early lenses. AI conversion kit #47 for the Nikkor-Q 135/3.5 is only compatible for lenses with serial number 831211 and higher. In general, AI kits were only made for lenses made from about 1967 onwards. I assume this when when the aperture ring changed from the older screw-on type to the ones which lift out when the mount is unscrewed.
