Porro v roof

revolving dioptre

If you unscrew the top, probably Bakelite, eyecup you will likely find three small grub screws which secure the dioptre to the lenses.

tripod thread cover

Certainly try asking Nikon for a replacement but any tripod thread cover will have the same 1/4 inch Whitworth thread. So if your local bino / camera shop has a cover it will fit but it may need to...

tacky finish

It's not just on Kowa scopes. I have come across the same problem with 'painted' binoculars. As already mentioned, you can remove it. You could try talcum powder.

faulty alignment

When a binocular is bumped or dropped, it is often the prisms that move. If the plate on which they are fitted, is a bit too big for the size of the prism than the images can be mis-aligned and...
