Ok, had a look, and it's from 1936, see scan of page, those are the frame numbers, that is the second number down from your headstock plate, the top number is the original engine number, so engine has been replaced at some point, but this happened a lot after the war. Have no idea about the DVLA, as I'm in Holland, but can imagine if you add these scans to your application they can see that it is from 1936.
