I just posted a new video from my darkroom deconstruction of 4x5 film holders. I had a couple that were too far gone to fix and thought they would make a good tutorial.
If you always wanted to know the twiddly bits of a modern 4x5 (5x7, 8x10) Fidelity or Lisco film holder, then take a look. It shows how careful we need to be with dust on our darkslides... once dust and grit is dragged into a holder light trap from the bottom, it's probably not coming out.

Then I filmed myself "fingerprinting" my 4x5 holders. I have a lot of holders for HABS/HAER work and when something like a light leak, or errant thread go haywire in a holder, "fingerprinting" lets me track down the holder to the exact side I need to inspect. I make tiny imperceptible nicks/dents in the hinge-edge of my film holders that can be seen on the edge of the film with a 10X loupe if needed. This is an evolution of the deep "code notches" marks I made in a few of my film holders at Brooks Institute when I was starting out. I'm now not a fan of these big notches; for code notches to be useful I'd need to come up with a code system for 200+ holders, no thanks. Besides, I now value the perfectly clean edge of my film rebate area (every HABS/HAER photo is delivered to the Library of Congress with the film edges visible in each contact print and scan.)
