Okay so I picked up a book at a garage sale today as part of a box, and it turns out some one has it wishlisted. Sorta.

Here is the thing the one I have is a two story in one, but its from 1945 and has no ISBN. Its 50 years old and in excellent shape. Someone here has the first story in the book wishlisted. But they have an ISBN, and mine doesnt and mine has another story by the same author in the book as well. But being as how both books are copywright 1945, would be hard to find. How do I let the person wanting this book know what I have and see if they want it? I know the ISBN would flag them to tell them its in the system but since I dont have an ISBN it wont tell the other member right? Anything I can do? This book is in completely amazing shape, and my thought was if I was waiting for a book that was 55 years old I would love any copy even if it had 2 books in one. But there is no way to let the other member know right? Am I missing something here?

No, there's no official way to contact the other member. You can post in the book bazaar that you have it and there's a chance they could see it.

You can also put a tag on the book that they have wish listed that says "alternate non-isbn version available" or something like that.
