I’m not sure why I didn’t think of this earlier, but there is a place called Century Farm Orchards that sells a wide variety of heirloom trees, and many of those are early ripening. He might even have Striped June. You can Google the place and find it easily. BTW - one early apple you want for sure is Bevan’s Favorite. The taste is much better than Striped June and it is only 2 weeks later.
EDIT - I just looked and he has 70 Bevan's Favorites in stock on MM111. He has 3 Summer Champion, and I highly recommend it as an outstanding (and big) early apple. I've never eaten a Early Harvest, but lots of people rave about them. He has 15 of those in stock. He has 65 Grimes Golden in stock. I ate my first one of those this year and loved it - not extremely early, but mid summer. That tree grows extremely clean for me here, and doesn't seem to be affected by Scab or CAR. I've also never seen any FB on it, but it is still too early to tell for sure on that.
