Beth, Love, love, love what you've done to the rows! The machine you added looks to be a Singer 29- used for leather work, boots, shoes, etc.
going a bit batty on a project I'm working on so hoping you have a 'spot' of something good in that teapot ;-)
The little machine in the second row from the top is a Willcox & Gibbs. It does a chain stitch. Might be putting her to use on my winter bowling league team t-shirts -Lucy, Ethel, Laverne & Shirley ~giggle~ We're old, not too fast but pretty darn good. We came in 2nd out of 16 teams.
best,
