I got a hold of another one of these, but I *still* don't need it :LOL:
This type is great because you can use it like any 4x5 film holder and slide it underneath the GG
Mechanically sound, but cosmetically some scuffing on the camera-side plate, and the worst part is the dark slide that has some rust/corrosion going on. You' might want to sand the whole thing down (and perhaps paint).
The last one I sold went for $100, so I'm thinking $75.
