Want to Buy WTB: Nikon F4 accesories

I want to complete my unused Nikon F4 landscape of accessories with:
-battery grip MB21
-waist finder DW21
-6x finder DW20
-rubber for sport finder DA20
-databack MF23
-focus screens K,J,...,Gx.

I want scratchless, mint to pristine condition fully functional items.
Anyway scratchles but defective MF 23 is accepted ( i will buy only for case to swap my MF23)

I pay fair price for pristine condition but don't ask for an arm and an leg.
I will wait as long is necesary to find those, any single item .. welcome.
Thanks.

hi, i have the following items from a friend:

Nikon PB-4 Macro Bellows/tilt shift movements
330€

Nikon PS 4 Slide Copying Adapter PS-‐4

110€

Leather bag 55€

Thank you for offer.
I have PB6 so I will buy only PB6 compatible slide/film duplicator adapter ( PS-6 ).
I really need PS-6 since I bought 3000' 35mm negative film.
