Know of a black barrel Nikkor-PC 105/2.5 non-AI for $159. Glazer's Camera in Seattle, WA has it. Looks to be nice. Tried it out on a Nikkormat FT2.
Are you 100% against owning anything that's factory AI'd? Reason I ask, there is a 300/4.5 Nikkor-H at another shop that I previously owned. Was a decent lens for film photography. Has the factory AI ring on it, but with the period correct solid coupling shoe. Also is Nippon Kogaku and has the period correct caps on it as well. Silver metal Nikkor 72N cap, and Nippon Kogaku rear cap. $149.50, IIRC for that one.
Personally, the only non-AI stuff I have are a couple F bodies and a Nikomat FTn that was just overhauled and converted to 1.5 volt. One of the F's is going to be listed here in a few minutes, and the Nikomat is listed, but is an old ad.
