Thanks for the responces. I guess I got a little confused. When they said Bound book, I'm thinking a book with a binding like a hardback or paperback novel, where the pages aren't easily removed without evidence that something had been altered. Then there was some mention of guns in my personal collection being sold after 2 yrs and I got to thinking my personal collection was something different than the guns on my A & D book, so I might have to enter them as a disposition to myself, then keep them 2 yrs before I could do something else with them. Now I understand the A&D form IS my personal collection (just a list of arms I aquired thru channels other than usual paperwork).
Then the Original Configuration clause got me. I guess that applies to arms that are on the list that are less than 50 yrs old.
I wish they would publish a book that was dedicated to C&R rules only, instead of having it all cluttered with all the other classes of FFL.
AREN'T THE M16/AR15'S COMING UP ON 50 YEARS OLD 
My understanding is,ANYTHING you aquire that is a C&R MUST be logged in the book. Its not that you "used the license" but instead you "are licensed". If its not a C&R presumably it does not count and it does not have to be entered. Thats an interesting question though,because what is and is not a C&R can be up in the air. Clearly a brand new Taurus revolver is NOT a C&R and anything over 50 years old IS one. Heres what the ATF website says.
Q: What is a firearm curio or relic?
Firearm curios or relics include firearms which have special value to collectors because they possess some qualities not ordinarily associated with firearms intended for sporting use or as offensive or defensive weapons. To be recognized as curios or relics, firearms must fall within one of the following categories:
1. Have been manufactured at least 50 years prior to the current date, but not including replicas thereof; or
2. Be certified by the curator of a municipal, State, or Federal museum which exhibits firearms to be curios or relics of museum interest; or
3. Derive a substantial part of their monetary value from the fact that they are novel, rare, bizarre, or from the fact of their association with some historical figure, period, or event.
A Charter Arms 38 special revolver made in the 60s is NOT a C&R. The one that shot John Lennon,as macabre as that is,probably would be under the third definition. What happens if ATF disagrees. If its a grey area,then you could of course purchase it using normal procedures,background checks ,shipping to a FFL dealer etc. The issue that I wonder about is logging. As an example,I have a old Sears JC Higgins model 21 shotgun. It has couple of Quail crudely engraved on it as well as two peoples names,Clark Mangum and Jerry Mangum (both have the same last name). To me this means nothing. Suppose for some odd reason,ATF examines my collection at my home (I understand that usually,its done at their office) and notices the shotgun. The agent says,"oh,that shotgun belonged to noted artist C Mangum,who painted hunting scenes involving ducks and in fact,that very shotgun,with the quail engraving appears in one of his paintings being held by his son Jerry. Thats a C&R as per defintion 3,why didnt you log it in your book?" I of course am thinking what the heck,how would anyone other than a art collector KNOW anything about who this guy was?
I agree that such a situation is implausible. I can just imagine that someone had a bone to pick for some reason though and was "looking for an excuse" to make your life miserable,like say,God forbid,you sold someone a Mosin Nagant sniper rifle,and he turned out to be a nut that committed some terrible crime then killed himself,leaving a lot of very angry Los Angeles police with no one to take it out on,except perhaps the guy who sold the gun.
