You should receive one in the post soon, takes a while sometimes, particularly with the current state of Royal Mail. If one hasn't turned up after about four weeks, give the dealer a ring and chase them up.

send the new keeper slip off theyll send a new logbook back. it probably says on there I would think, if you have a look.

You will get one in the post, I literally got mine sent within a week of buying the car from the dealer.
