I’m pretty sure they are crab apples. I made this photo and put it on Facebook 'cuz I didn’t know what they were. Some folks were very familiar with them. There are two trees, two kinds, right next to each other…pretty much ‘in town’ but A) they’re hanging over the street and the sidewalk (that’s barely there) and B) it’s a rental property, C) I can at least get a taste and some seeds, D) should be easy to get scions, too.
They look like Callaway but they’re more yellow. My callaway is usually completely red.
