Nite Finder, excellent. Take out the batteries and remove all the shell screws. On the NF they're all the same, so you don't have to worry about remembering which goes where.

Unseat the plunger tube, two small screws, fore and aft. Save 'em separately. If your NF is old, the plunger and barrel are either just pressed together, or some have two small screws holding them together. If it's newer, you'll have to dunk the barrel end in a pot of boiling water for 20 seconds, then with work gloves, wriggle the two pieces apart at the seam. It might take a couple of dunks and a few tries.

Get to this point and I'll send you more instructions.
