Agreed . That blue is way too nice for original .
The decal is wrong for the year of your bike . It was used on the 1952 model ONLY .
I believe the decals for your year should be , one each side of the tank , see the image below .
In 1955 there was a special anniversary tank decal used on some models . I suppose it's possible that if your bike is a very early '56 , it 'might' have had those . I don't think I've ever seen that special '55 decal .
By the condition , I think the wheels are original paint .
Pete .
