Well it has the 46 to 48 yokes. Cylinder has the smaller base so it's a 350 the tank colour looks the same as the rest of the bike so black. I thought the NG had girders in 46 where hunters at teles that year the ng gained teles in 47. So my money is on 47/48 NG.
John wrote "I thought all the NG s had black paint rims." Yes NG rims are listed as black and gold, NH as chrome and red Also the bike is fitted with red hunter mudguards and not the valanced deluxe guards so for me NH Petrol tank? David
