A seller is selling an arca swiss 171 camera with various accessories, however I cannot seem to identify them based on the picture the seller has provided. Could you identify them (Items 1-7)? (Only have this small picture)

The seller states the attached items include

- Large-format camera ARCA SWISS
- Geared Head (! Absolute Head about 5 kilos)
- Quick Release Plate Adapter for Ground Bar
- Compendium including filter holder
- Polaroid cassette
- Roll film cassette for 4.5 x6cm
- Kodak Ready Load Pack
- 16 pieces of 4x5 inch sheet film cassettes
- Polaroid and sheet film packs some (older use-by date)


My guess

1 ? an example of 4x5 film cassettes ? what type are these ?
2 Arca quick release clamp? Genuine?
3 Polaroid cassette?
4 Roll film cassette (4.5x6cm did arca make these? The darkslide seems to be for 6x12 size? )
5 Compendium hood (is it 6x9/4x5 version or 4x5/8x10? How can one tell? where is the filter holder?)
6 Kodak readyload holder + film?
7 Geared head? What type of head is this? I have never seen one?


Your help is much appreciated. Thank you in advance.
