Hello, [MENTION=412886]PierreSeb[/MENTION], welcome to the forum! Sorry about the Rickert, but with a 1965 Super Course you're still rich .

Do you have any pictures of your bike? A serial number too, would be most welcome to help date other RIHs.

And with regard to the decals: if you're having them made, I'd be interested in a set.

The bike in your link looks to be a Fongers-made RIH (111T?). They were often red. I'm not sure if it's the same color that was used by the Amsterdam shop.

I have a red '68 Fongers RIH that I could take to a paint shop and see if they can match it to a RAL code. It is a little faded though, so I'm not really sure if that would work.
