Could you post all the data that is written on it?

Such as "Nikkor 200-400mm f/3.5-5.6 AF"

I'm not aware of any f/6.3 Nikkor telephoto lens… But that 1:6.3 also might refer to the magnification ratio, not maximum aperture.

You might have either junk or quite a gem there, so knowing the exact specifications will be important.

Perhaps you can find it on this list:

Edit:
That H71287 lens serial number doesn't seem to match this list:

Probably it's not worth much then. It might even not be a Nikkor lens but a third party one.

If it comes with a Nikon F-mount then it can be mounted on a dSLR.

That's a long lens if I'm not mistaken and it should come with its own tripod mount.

It's unlikely to be a Nikkor.

The 400mm f6.3 preset is a nice piece of kit, and with the right adapter will mount on any camera, but it's not worth much - I occasionally use mine (originally bought for Pentax) on my Canon.

As long as it works and is in pretty good cosmetic condition, it should be.
