-SG- In 1929 and 1930 many standard 'non-cradle framed' Nortons were supplied fitted with Lucas electric lights and MDB1 magdynos. Indeed, my 1930 Model 18 was so equipped when I first bought it in 1956. Although the magneto part functioned well enough when I got the bike on the road a couple of years later, the dynamo gave periodic problems. I did not have access to Lucas's period instruction book which might have helped ... Thanks to Ian, a scan of this publication is now available. Much appreciated as always!
