I have been thinking about lighting kit for the ’28 Model 90 and came across this original Lucas document on the usual auction site. The title is : Running Instructions For The Lucas “MDB” Magdyno Lighting And Ignition Set for Motor-Cycles 1929 Equipment. So, I scanned it and posted it here in case anyone else is interested.

I think I need a Lucas SS49 headlight or headlamp to be correct for the year, there are some very nice replicas available from Vintage Replica if I fail to turn a genuine one up at sensible money.
