I've now fitted some new parts in the gearbox and cleaned up the cases. I had forgotten what a nonsense these are to fit/remove!! Much improved by Royal Enfield on later models by simply slotting the bottom lug. I had to refrain from doing it to this box in the name of originality. I have a few more bits painted and much more enjoy the build up over the cleaning, stripping, welding, filling, sanding and spraying. One of my next tasks will be to modify and make fit my Indian made Model G air box. I'll post pictures as I go. Ron
