Hi Brian, About five years ago during my quest to obtain another Hogan RCA 350 twin cylinder two stroke engine I met a man called Dave Benson from south London who had one for sale, Dave Benson had a serious collection of motorcycles at his home, a large proportion of which were Villiers engined pre-war machines, one of these was a Francis Barnet with a 1T twin cylinder engine, from memory this was an inline engine, Dave pointed out that he had terrible trouble getting any lights working untill he found out that it had a four volt system, where he obtained four volt bulbs from I didn`t dare ask. I also doubt very much if this machine had any Lucas equipment fitted at all but I may be wrong. Alan Noakes.
