daverclasper Posted April 12, 2019 Report Share Posted April 12, 2019 Hi. I'm looking to buy one of these at the right price over time, (probably secondhand if known to be ok). There appears to be different specs. Amps, (my dynamo apparently is 25) Then different sub/parts no's - NCB 136, 37592, 37577, 37503 and VRG 3606. Have looked in FWM/Haynes and doesn't appear to go into detail (Just mentions RB 340). Any clues please. Thanks, Dave Link to comment Share on other sites More sharing options...
