Yes, the Gold with black scallops was the stock color for the Bonneville in that year. I think that there may have been a different color scheme for the other models but I don't know what there were.
I just finished mine and had the paint matched by my local supplier. I was lucky in that the underneath of the tank was in pretty good shape and that gave them something to match to.
is one of the better suppliers of correct paint for Triumphs in the US but I don't know if he ships to Canada.
Do you have a local supplier that can match for you or would have paint chip books to choose from? The paint is metallic so keep that in mind.
Here is a link to my rebuild, perhaps the colors on the web pages will help you. I was never a fan of the black scallops so chose a different color for them however the gold is still pretty close.
Good luck with your project, Art.
