I don't have a clue about your cams.... sure look like a nice assortment. I'm surprized that there isn't a name somewhere on something.
I do have good news to report. I did some hand sewing on my cathedral window quilt yesterday.... YEAH!! It is slow going but I was able to thread the needle, make a knot, and stitch. It felt so good to have a needle in my hand. Now, I need to try using one of the machines. Thanks so much to all of you that have wished me well with my arm. I'm still making progress.
