As far as the components are concerned; the crank is "Sugino", the rear derailleur is "Suntour Seven", the freewheel is "Perfect", bars are "Sakae Custom". It had the old two position brake levers which I removed and replaced with Shimano Dia-Compe hooded levers. I have no idea what the vintage of this bike is, but I guess I could find out from the serial number stamped on the bottom bracket.
Thanks for your info.
