Yeah, the handlebars are original, apart form the Grab On foam, as are the the Dia Compe brakes/levers and Suntour shifters/derailleurs. All it really needs is... all the parts that make it go: chainrings, cranks, pedals, cassette, wheels, tires....
I am pretty sure that "Rob" won't be able to source original parts for most of that, but maybe over time I can!
