Can someone tell when the first appearence of Earth 1 Batman is in both " Batman" and "Detective." Is there a definitive issue? Whats everyone think?

there is none, because the Earth-1 Batman was a retcon. He was always the same guy, until the multiverse became more and more popular so they explained that the Batman of the 40s and early 50s was the "Earth-2 Batman" and the new one was the "Earth 1 Batman".

dcindexes.com says earth one batman first appears in superman 76, though truetothecore is pretty much right
