I don't know the color scheme you may have had in the US, and it seem to be a little different in different parts of the world.
The picture from Norway show the colors for regular up to 1958, the premium colors of that era was the same green on the lower parts of the pump and the upper half was white. The decals were BP with black shadow.
From 1958 an onward the regular had a lighter green on the sides and top and white doors. Premium had yellow sides and top and white doors. Decal was green and yellow BP with a slightly different shape of the shield and NO shadow.
Don't have any codes, sorry, but I am sure Guidos codes match very well.
I could possibly be of help with the older type of BP decals that are readily available over here (Sweden), the newer ones are also available but I have only seen them on swap meets, can take a while.
