Vintage camera lens. Nikon?

I have a huge nikkor-q auto 1:4.5 f= 400mm lens made in Japan. Does anyone know the value of it? Http://twitter.com/danyele88/status/234778963686330369/photo/1

It is a very old lens and may not have been converted to an AI lens.

Finding someone who can use such a lens may be your biggest challenge.

It cost $398 in 1959
