I think you're going to have a difficult time replacing that kind of part (unless its cannibalized from another existing scope which I can't find) or if somehow it could be fitted with a generic adjustment knob but I have a feeling you might be missing more than just the knob itself. If you like that particular style of scope there are other options out there (Nikon makes some to)
