Hasn't any one seen one or knows what it looks like???? Prior to 1931 the engine was fitted with a ML magneto and from about half way through 1937 they were then fitted with a Lucas RS1. The ML magneto syndicate was purchased by Smiths Industries in 1919 which was then sold to Joseph Lucas in 1930 or early 1931. When Lister had used up their stock of ML magnetos they fully changed over to Lucas MK1 by July 1931. I have been led to believe that the Lucas MK1 was similar in appearance to the ML but not having seen one I do not know. Can any body shed any light on the subject for me?........ Cheers ..Phil
