They still won't understand even if you send a covering note, the DVLA ended up with the V5 for my shell and would send it back unless I had it inspected with all the correct parts on that I had moved to another shell. I re-applied for the log book recently and they sent it through.
They haven't got a clue at the DVLA I've spoke to one person before who told me one thing when I rang again I got a different person who told me something else needless to say I had an argument with them.
