Nikon Bellows: PB-3 and PB-4, and unknown mount - SOLD
I have these available at no cost to anyone who is able and willing to pick them up in Kingston Ontario and give them a good home. (I don't want to get into shipping them). They are dusty as they were in storage for many years but appear fully functional with a smooth movement of the mounts on the rails.
