That bottom Singer is a 414g? Looks like a 404 but made in Germany - those were most likely a 'beginner' machine a - just a simple to use straight stitch - a lot were probably used in schools late 50s and early 60s. They are a wonderful machine. They have the same slant needle as the 301, 401 & 500 so all of the accessories fit it too. It is easy to see the needle because of the slant and they have a very nice light. They are a straight stitch only. They are also light weight - about the same size and weight of the 301. BUT what I like is the drop in bobbin - so easy to use! It takes the class 66 bobbins. I bought out a school full of them a couple years ago. My grand daughters and great niece each sew with one. Some day they will graduate to 400's or 500's for the decorative stitches I'm sure.
