they are always fun to identify - I can see some New Home and White, along with the Singer stuff. ONe metal box has the "generic" set and one of the cardboard boxes is most likely Free or National - so you do have a wide range there.
The truley fun part is if there is one of the rarer attachments that don't normally come with a "set" included. And it's also fun to figure out what doesn't even go with sewing machines LOL!!
