^^^^ Maybe the specs were different in the US. The one with the fully chromed seatstays is the Pro 10, there was also the Vitus PY FC, so the steel PY (PY 1O M, I think) was not the top model anymore. Yours looks like a 1985 PY 10M. I'm pretty sure mine's an 1984 because of the combination of "red" and "green" Reynolds tubing for frame and fork (5/10 mm and 7/10 mm), that was only offered that year. Looking for a catalogue pic...
