Beautiful. I have one that I got free and restored and I absolutely adore it. I have put a zillion miles on it, I love this bike because it's so gentle on my aging body. I am a bit jealous- yours is a 58 CM and those are pretty rare around here. (CT), Mine is a 62 CM. All the above advice is solid, as usual. I have swapped various wheels on mine, and I like the old Rigida rims better than the Arayas, (in 27") they seem to stay truer .
I sort of skimmed through this thread, I assume there's the usual lecture about the bottom bracket in there somewhere.
Yeah, get that hub play fixed, that can cause high speed wobbles on descents, and you don't want that. Make sure you lock that bike up real good. Not a bad idea to lock up the panniers and the saddle as well.
My Moto Super rides better than some of the other bikes I had that had "better" tubing. The way the french did their construction and geometry was so utterly kick-ass. Enjoy! very, very nice.
