chrisannesam,
Well, you asked for it!
You have the wrong front guard, your seat shouldn't have piping and if your tank badges are black ,it's hard to tell, they should be dark green.
You are correct in saying the frame should be dark green, don't know if it was BRG.
Shame about the hubs as the Ariel type are much better looking.
The one that you looked at on u-tube has a few things wrong with it so maybe shouldn't be used as a yard stick if you want 100% correctness.
Still looking, the resolution is not quite good enough for enlarging, the oil level sticker seems to have too much writing.
Do you have a manual advance magneto? I can't see a lever for one.
Nice job and if it goes as well as it looks you will be very happy.
Trev.
