The red bike from the OP is not a proteus from MD, thats a fact. Totally different built and style, the red one is probably mid 80's, mid 90's racing, I would love to ride that red proteus. At the opposite, you wouldn't pay me enough to try the ones from MD , Just being honest!.

That red proteus is really well made, I agree with unworthy1. Next time I'l be looking one of those too, good find! I HATE YOU! hehehe

Ok, U-scanini and now proteus from uk or whatever added to the list
