Rob, that's my feeling too, which is why my Ni-Fe box is on the shelf.
There may be a difference in the number of coils, but the Lead-Acid type changed over time too.
Nortons and Triumphs with their clip fitting regulators on the frame tubes are probably the only two makes where the base can be clearly seen, especially where the white infill is present.
Engraving would probably be needed to replicate the marking. I can't imagine that any form of letter punch would give the correct depth and profile.
Royal Enfield don't seem to have used the loose cross straps on WD/Cs, but their battery carrier had side projections anyway. They do though seem to have adopted the standard cover with welded-on strap when it became the norm. The 'D' would probably have been the only Ni-Fe period RE.
After riding with an 8 watt headlamp bulb the glow from a blackout mask must have made them feel quite at home...
Having ridden my bikes at night over Dartmoor many times (without any streetlights) but with a standard 6 volt Lucas set up I don't think I'd relish any less lighting..It's nearly impossible to see the sheep, cows, badgers, rabbits, foxes and ponies as it is!!....:milky_way: Ian
But after discovering my project bike was produced after it’s discontinuation- I am unsure what to do now - it was another nice feature along with the big battery I had wanted on my bike
