I read all parts of the series many years ago... so I 'probably' still have those F&SF magazines... in boxes of old SF stuff which I am planning to give away..(as no one seems to buy old paperbacks any longer). There is a place called "Friends of the Library" here which takes in gifts and sells them cheaply to benefit the library.
I am in the Wash DC area, and would be glad to share any or a thousand or so SF books and magazines.... but fairly soon.
