It's from a kid's tool kit, if I'm not mistaken.
Not sure if your joking or not, but that was actually what I was thinking. Maybe some type of junior woodworking kit.
Disston made some small saws for boys marked "American Boy." Other small saws, that I know of, were toolbox saws, but not kids' saws.

Here is a terrible iPhone photo from the 1932 Disston catalog. As you can see, you have a #28 Tool Box Saw. Now you just have to find a #29 to go with it.
Oh wow that's amazing thank you. I thought for sure it was a kids saw of some kind. Would something like this potentially be collectible? If not, I'd love to use it as a crosscut saw at the bench.
