In reply to Samuel Wainwright:
Not entirely certain but there are two things I would do: email MTE/MTA and put the question to them, or simply photocopy an old logbook sheet if you have any spare. Which ones are you looking for? I could send you a couple (got a fair few still not written on). DLOG is being pushed a fair bit now after the effort they put in to getting it going.
Cheers
Jim.
