Hello Dillo 27,
Here are some shots of my Coureur in the Belgian colour scheme, frame number #9081. I’m pretty sure it’s a ’61 although it is possible it might be a ’62. The Nervux lugs are different to what you have but with your number being less than 3000 frames latter, I guess you are looking at a ’62 as by ’63 the French Prugnat lugs had come in.
So for my 2 peneth I’m going for a ‘62 European
Also I'm pretty sure this transistion to the Prugnat lugs brought in the olympic rings (with yellow far left) seat tube transfer as per my sons '69 Electron super five (see yellow photo)
