Ignore Swansea mate, the numties on the phone can only handle the common obvious questions and then they get them wrong over 50% of the time. Note that they have only recently confirmed that vehicles that have never been Sorned, of which i have several, do not come into the "Must insure or sorn" category
If you go to put it back on the road take the old log book with you to MOT station then take all paperwork to your "Local" DVLA office (N.B. "Local" can be 50+ miles away!!) and tax it there, you may get hammered for the registration fee but should all go through with no problem
