Agree that this was a mid to low end Japanese imported bike from the mid 1970's. Don't know if they made it into the 80's. In my area, New England, they were sold by a wholesaler in Massachusetts who also sold Austro-Daimler-Puch bikes. Whew ! Say that 3 times. The bikes were OK and all used the standard SunTour derailleus, Dia-Compe brakes, etc. Nice quality and finish. The Japanese drivetrain shifted a lot better than European imported bikes of that time period. The brand came and went rather fast. Parts, and it sounds like you need all of them, should be no problem as to interchangeability, etc. Hope that this helps
