Okay, here are some pics of the two that are still unidentified. Sorry about the fuzzy pic on the second; I took several and the camera just did not want to work with me.

better pics, thanks. As BKrenning said, the top one may be an accessory of some sort since it appears to be no way to connect it directly to the machine. I'm not familiar with the bottom one.

The upper left looks like a "darning" foot I had with my old Viking.
