Recommend you phone Grace Popplewell (note spelling!) see her ph here:

She is very efficient and knows how to navigate the infested waters of dvla, who having closed all their offices are in a state of complete chaos.
I started my reg process via Grace in Aug, still waiting... first they sent me a V5C for my 'unlicensed' tractor - there's nothing you can do with it coz it says it's 'unlicensed'.
So sent it to Grace who wrote letter and resubmitted to dvla, requesting 'unlicensed' be changed to 'vintage'.
more waiting... V5C arrived, but there's no number on it. More waiting.... another V5C arrives, this one undated. Sent both V5Cs+ insurance cover note to Grace who resubmitted requesting a valid V5. ....Still waiting.... told there's a 2 month wait as they are busy with all the new car regs.
So go with Grace but be patient....
AND Keep a copy of everything you send...
