Hello, just have a few questions. My uncle (who recently passed away) had this bike in his garage for the longest time. It is now mine, and the questions I have is how do I tell if it's Italian or Japanese made? Also I would like to find out what year it is, what model it is, and how much it may be worth? It's in pretty good shape other than the tears on the seat and a couple minor scratches here and there. If anyone could help me it would be greatly appreciated. I can post more pictures if needed..
