I have been working out of a copy of the Elston Family Book for the past 22 years.( I have an original copy of the book) I had it in a 3 ring binder. Some of the holes on the pages need to be re-enforced,however all the pages are there. I'm willing to sell this working copy for $15.00 plus postage. I do not know how much it weighs, I will get it weighed with in the next day or so and let you know. I have the CD, and I have it working the way I want it, so I don't have a need for the working copy any more If you are interested please let me know by return mail.
