Just picked up this Apollo Custom Sport for $140......

Hopefully it wasn't over priced, but i just loved the opportunity to clean this up and bring it back to its former glory. It appears to have most of its original hardware as follows :

Shimano Selecta crank set
Shimano 500 front and rear centre pull brakes
Shimano Altus-LT gears
Nitto Olympiade 113 bars

Does anyone have any idea on the age of this bike?

This will be my 1st project bike

Thanks
