Yeah, I hear you. I had gone through a few pdf's looking for the Super Competition and was getting confused. It was about that time I read on another site about the Super Competition being the px10. I had also noted the placement of the decal which as you say was towards the seat tube not head tube.

I guess it doesnt matter all that much but I would hate to go and remove bosses, respray and singlespeed what I would later realise is a quality road bike that deserved to be restored instead
