Ah, it's good you realized the potential problem, though it is unusual for
the tab to allow mounting non-AI lenses (Nikon could have avoided the compatibility problem so easily [on cameras with DOF preview] by designing
the camera tab to miss the rear of non-AI lenses).

You could look through Shutterbug classifieds for pricing, but I would guess
that all would go for under $100 each (the 135mm f3.5 AIS sold NEW a few
years ago for well under $100!), unless unusually old, or in really mint condition. The newer 105 is considerably better, I think, than the
small rear-element version of the old one. They are all very early designs,
and while good, newer MF versions are crisper, with more snap (not true
of most of the less expensive AF zooms, though, alas....).
