I just bought the same orange Star bike. After reading this thread I and trying to identifey the manufacture of the bike I did find a Miyata seatpost bolt. So I'm sold. These things were made for Star by Miyata and the loaded them up with high end components. I like the lug work, the qulaity Shimano components and mine also has a BELT Fujita Leather saddle. Serial # on this bike is: 9393213. Based on components (see above list) I'm guessing it's a very early Miyata import. Okay, I know what it is and it's cleaned up and ready for it's initial road test. Chow! Thank You all.
