Need some help with equipment

[billy001]

Hello everyone

(first of all, English is not my first language, so i`m apologizing in advance)

Few days ago i found several of this things (I guessing those are film holders) on my attic.
I don`t know a lot of film photography,so I`m wondering what are those exactly, are they sill in use, and do they have any value at all.
The one I photographed is not in the best of condition, but other 6 seems to be unused.







many thanks

they appear to be part of a film holder. no value as they are.

At first glance i thought they might be the slide portion of the holder, but they shouldn't have ridges just a flat piece of metal.

In 4 of them i found what appears to be a film, i`m guessing ? :???:

They appear to be old large format film holders or parts there of, probably not of much value to anyone as new ones can be had relatively cheap.

Yes, they're film holders.
