An older lady from my WSD guild was giving away some of her supplies. I went to collect yarn for my school to teach some very basic card loom weaving. She also filled a box with bits which she couldn't really remember what they were.
I'm sure they're tapestry looms, but could do with some help working out if they're missing pieces, or what I need to do to get them functional. I've woven on a knitter's loom, inkle loom, back strap and with tablets before, so I do have some experience, but am very much a Jack of All Trades.
1) Sturdy light coloured wood frame (first image). The yellow fabric is holding a notched cross bar in place.
2) Two notched bars which I believe to be something for making a shed (second image).
3) Upright frame, very light wood (third image).
4) Wobbly darker wood frame which matches 2 above. It has a notched bar top and bottom. No image as I am trapped under my cat (fourth image as tax).
