WTB: Nikon DW-2 6x Chimney for F2, F2sb, other stuff

I'm looking for a Nikon DW-2 finder. This is the 6x "chimney" finder that fits the F2. Cosmetics don't matter as long as it's functionall and has clear glass.

I've posted this a few times, but I'm also looking for an F2sb, or otherwise a bare DP-3(complete camera probably preferred). If a complete camera, I prefer nice condition black but either color is fine.

I'm always looking for unusual or oddball F/F2 accessories including special purpose focusing screens(I have most of the common ones, but will consider any if they are cheap and will pay fair prices for good condition less common ones).

Finally, I'm always looking out for pre-AI lenses. My main interest at this point is unconverted "early" lenses with fluted focus rings-both rare lenses and common high condition examples. Nikkor and/or Nippon Kogakua caps are always a plus. I am also open to AI converted lenses, although I personally devalue milled aperture rings pretty seriously(i.e. I prefer conversions with a factory ring).
